Some time ago, I made a 40-key "simplest programmable in-line keyboard with RGB". There are cheaper plans, and this time brings a new one. The circuit diagram is as follows, directly designed and drawn on JLC online, the circuit structure is relatively simple. This project uses the relatively cheap Atmega32a chip as the onboard main control. The single PCB has 16 keys, and the same circuit board can be spliced ​​left and right to form an in-line keyboard with 32 keys, 48 ​​keys or 64 keys. Among them, the main control and the type C port are welded on the rightmost PCB. A must-read for getting started! ! ! A must-read for getting started! ! ! A must-read for getting started! ! ! For the specific production process, please refer to the original project: "The simplest programmable in-line keyboard with RGB" Production order: The keyboard is made of 3 pieces of the same PCB spliced ​​from left to right, and the size of the PCB meets the requirements of JLC for free boarding. Weld all components except the key shaft; Mainboard burning BL, firmware, debugging; The key shaft is stuck on the positioning board, inserted into the PCB, and the two adjacent circuit boards are spliced ​​together by wire welding; Test whether each key is working properly; Weld all key shafts; Shell installation. Precautions for welding installation: The soldering of Type C and 32a chip is a bit difficult for Xiaobai. It is recommended to use a heating table and solder paste to complete it, which is much more convenient than an electric soldering iron. Except for the key shaft and individual components, basically everything can be done with a heating table. Solder this kind of small board, apply solder paste to all SMD component pads, put the components except C port and 32a chip, heat, wait for the solder paste of C port and 32a chip to melt, scratch with a sharp object if there is tin Turn it on, then place the chip and C port accurately, press and hold for a few seconds, and solder all the patches at one time, 100% successful, fast and good! Those who are inexperienced can search for related content at station B to learn, and pay attention not to solder too long to avoid damage to components. The heating table shown in the picture above is from a treasure, DIY a PCB heat insulation bracket, simple and practical. The upper and lower case LED lights can be soldered to any position of any PCB, and the resistor R7 is welded on the PCB. Other boards do not need to solder the upper and lower case lights and R7. The welding method is as shown in the figure above. Don't ask me why I use in-line components, it's because I still have a lot, such as self-modification using SMD packaging. The key shaft adopts the high-tech standard shaft, which is directly welded. If you want to use hot swap, you only need to simply modify the hole size of the pad in the sleeve method. The shaft seat method is not recommended, and the change is large, and the position around the chip is small. . Just use wires to weld the two PCBs together (note the order of production). ATmega32a and other master controllers without USB interface, before burning the firmware, you must first use the USBasp burner to burn the bootloader, and then burn the firmware. The USBasp interface does not require soldering pins or sockets. It is best if there are burning pins when burning the bootloader. If not, insert a common pin on the Dupont cable, then insert it obliquely into the PCB jack, and press lightly when burning. Anyway, it only needs to be burned once. BOOT and RESET use light touch switches, and there are small holes corresponding to the position of the bottom plate, which is convenient for burning firmware during debugging. If you don't need to debug repeatedly, you don't need to solder the switch, just use tweezers to short it if necessary. There are two designs of positioning plate and bottom plate for choice: it can be made by whole plate, which saves trouble; it can also be divided into two pieces, which is the choice of JP xx. The thickness of the frame is determined according to the actual measurement of the selected key shaft and the height of the circuit board and components. The key shaft is divided into standard key shaft and short key. After receiving the positioning board, bottom plate and frame, if necessary, fix them with copper pillars and screws first, and then sand them smooth with coarse, medium and fine sandpaper in turn. Do not polish the circuit board and key shaft after installing, otherwise the dust will enter the key shaft and affect the feel and quality. Burn bootloader, firmware: 1. The USBasp programmer burns into the bootloader. When burning, pay attention to the fuse bit as shown in the figure above. A brief summary of the steps is: initialization (select programmer, select bl file) - read - modify L, H - write - read - start programming, the bootloader only needs to be successfully burned once. Station B has a very detailed video explanation. 2. There is a compiled hex firmware file in the attachment, which can be burned directly. The generated hex file is burnt into the module with qmk toolbox software, the steps are as follows: Open the hex file. Select the MCU as ATmega32a. Click Auto-Flash Press and hold the boot switch, and then press the reset switch. If the circuit board is soldered correctly, the programming will start. Wait for a few seconds to complete, and release the boot. Press the reset switch again, and the RGB lights of different colors on the bottom row of the keyboard will light up. Congratulations, the keyboard can be used normally. Complete the assembly: This is the final product, with a 9.9 yuan free shipping keycap, which is cheap, simple and easy to use. The bottom row of the keyboard is equipped with WS2812 RGB lights, and different colors correspond to different layers. Don't tell people, my aluminum positioning plate and bottom plate are from the next door neighbor JP's for free. Keyboard arrangement design: I always think that the key setting is the soul of the whole keyboard DIY. If you set it according to your needs, the small keyboard will be very convenient and efficient to use. 1. 16-key numeric keypad The left is layer 0, and when the left thumb presses the Enter key, it enters the layer shown on the right. Other layers can modify their definitions as needed. 2. 32-key auxiliary keyboard This auxiliary keyboard is especially suitable for right-handed mouse operation and left-handed single-handed operation. Other layers can be modified and defined by themselves according to needs. 3. 48-key full-function keyboard The keybindings have undergone several changes: In the first version, all punctuation marks are uniformly placed on the first floor, and the right-hand numeric keypad. In the second version, it is changed to a left-handed numeric keypad and a right-handed direction key, which is more convenient for the left hand to input numbers with one hand. In the third version, as shown in the scheme below, frequently used independent shortcut keys for copy and paste are added to the leftmost column, and media playback or other common shortcut keys are added to the rightmost column. The F area is changed to the middle of the 3rd floor, which is convenient for left-handed one-handed operation. Layer 0: letters + function keys, long press Fn1 to enter the number and punctuation layer, Fn2 to enter the arrow keys and punctuation layer, Fn3 for the F function area, virtual mouse, Fn4 for software shortcut keys and media keys. Press Fn1 and space to switch Chinese. When inputting Chinese, press the space with the right thumb to select the first word, press Shift with the left thumb to select the second word, and press Shift with the left thumb to input capital letters. All operations do not need to leave the main area. Compared with the previous 40 keys, the biggest change of this project is: the leftmost is the frequently used copy and paste independent shortcut key, and the far right is the independent direction key. Layer 1: The left side is the numeric keyboard, and the right side is part of the punctuation marks. All punctuation marks are arranged according to personal habits and easy to remember, such as ? It is the F position where Fa asks the question, # is at the J position of the number sign, ~curve q, @at, [bracket Z, {curly bracket K, Na N, $Us knife, "double quotation mark S, ... +-× /= Taking into account the use of the numeric keypad. When I started using this solution, it took a long time for my left hand to get used to it, but it is still worth it. Layer 2: Leftover punctuation marks on the left, arrow keys on the right. Now put both hands on the keyboard, press Fn1 with the left thumb naturally, and feel that there is a numeric keypad underneath, and press Fn2 with the right finger, and feel that there is a directional keyboard underneath, which is very natural and comfortable. Finally, when I used it myself, the rightmost column of independent arrow keys was changed to PLAY, NEXT, and two commonly used software shortcut keys. Level 3: Still the spare shortcut keys, F area, and virtual mouse. Press and hold Fn3 below with the left thumb, and then press the buttons in the middle 4 rows. I found that it is very easy to operate the keys in the F area with one hand. The 4th floor arranges media playback keys and shortcut keys for commonly used software. For example, Fn4+C runs Chrome, Fn4+Q runs QQ, Fn4+W runs WeChat, Fn4+M runs music software, Fn4+V runs video software... 4. 64-key full-featured keyboard, including a left-hand independent numeric keypad. On the basis of the above 48-key full-function keyboard, an independent left-hand numeric keyboard is added, which is suitable for the recognition and use of a large number of input numbers. Other layers are consistent with 48 keys. The above key settings are more designed according to the operation of the left-handed keyboard and the right-handed mouse, and the numbers, F area, and direction keys are all suitable for one-handed operation. All shortcut keys only need to be pressed at the same time, and a lot of space is reserved Shortcut keys for setting. Why is it cheap? The relatively low-cost ATmega32A chip is used as the onboard master control; The minimalist 48-key design minimizes the cost of key shafts; The splicing circuit board mode is adopted, and the size of each circuit board meets the free requirement; All 1U buttons are used, and the keycaps are simple and cheap, and there is no need to buy satellite switches; Simple structure, small shell. How easy to use? Well-designed small configuration, all buttons are within the comfortable operating range of ten fingers, and the little finger does not need to press outwards; The most frequently used enter key and backspace key are under the little finger of the right hand, which can be operated without moving; The button to switch between the 1st and 2nd floors and the shift and space bar are just below the two thumbs. The function of the thumb is no longer only used to press the space, and the utilization rate of the ten fingers is effectively improved; Press the Fn1 key with the left thumb, and under the left hand is a complete numeric keypad and arithmetic symbols, which is very suitable for left-handed numbers and right-handed mouse operations; Press the Fn2 key with the thumb of the right hand, and under the right hand are up, down, left, right, Home, End and other direction keys. The gesture is similar to holding a mouse, which is natural and comfortable. It is especially convenient to move the cursor position when coding; For all punctuation marks, you only need to press the Fn1 or Fn2 key with your thumb, and press the corresponding key with the finger of the other hand. All the keys are in the comfort zone of your fingers; Press the Fn3 key with the left thumb, press the F key with one hand is easy to use, the right hand Fn3 key, the virtual mouse... Of course, compared with the large-arranged keyboard, the small keyboard must be learned and proficient by oneself, and it will be convenient and efficient after the formation of muscle memory. The key setting is also getting more and more perfect in my continuous use. Attached are the verified firmware .hex files, and the QMK source code. iqirtryi32a_iqp32a.hex is the 16-key and 32-key firmware, iqirtryi32a_iqp64a.hex is the 48-key and 64-key firmware, zip is the corresponding source code. During the production process, I referred to a lot of information on the Internet, and thank you again for your contributions! Thanks to Yomen's open source project, the bl file USBasploader_32A.hex comes from his open source. Without his open source project and detailed explanation on station B, this project would not be so simple and smooth, thank you! Thank you for your attention, if you find it interesting, remember to like + comment + bookmark!

Looking back at the keyboard market in 2022, the Gasket structure is undoubtedly a hot word in the market, and major manufacturers around the Gasket structure have also started "fighting the gods". The domestic manufacturer Dareu has been constantly experimenting with the Gasket structure. After launching the fence-type Gasket structure for the first time, it has recently brought a keyboard with an elastic arm Gasket structure. It has really worked hard on the Gasket structure! Dareu's previous fence-type Gasket structure used a whole piece of silicone pad to wrap the PCB liner to achieve a soft and elastic feel. The newly launched elastic arm Gasket structure uses a PC material positioning plate with T-shaped small ears and high-toughness silicone. Combined with the cap, the smaller support contact makes the Gasket structure more soft and elastic in terms of hand feeling. This time 75% of the Dareu A81 three-mode wireless version is equipped with an elastic arm Gasket structure, which can be said to carry out the soft elastic feel to the end! The literal translation of Gasket is the meaning of gasket, so Gasket is also called gasket structure-the keyboard PCB liner is placed on a soft elastic gasket such as rubber, and the PCB liner is fixed by the pressure of the upper cover and the lower case on the gasket . The PCB liner of the keyboard is fixed by elastic gaskets, which will sink to a certain extent when pressed, and the feel is softer and more consistent, and the sound performance is also purer. Many friends will ask whether the value of the Gasket structure keyboard is worth buying. This depends on the usage scenario. If you have high-intensity text code input and heavy gaming hobbies, the Gasket structure keyboard is undoubtedly worth buying. The soft-bouncing experience can relieve the fatigue of long-term input. But it is not recommended for paragraph axis lovers, especially those who like the green axis. The Dareu A81 three-mode wireless version uses a dazzling silver packaging box, which is very stylish and recognizable. Open the package, in addition to the keyboard body, there are regular accessories such as a dust cover, a 2-in-1 key puller, a USB-A to USB-C cable, and additional keycaps. The Dareu A81 series adopts the current hot 75% layout. While retaining the F area and arrow keys, it discards the number keys and some function keys that are not frequently used, leaving more space for the mouse on the desktop. Different from the mainstream 75% arrangement, the Dareu A81 series adopts a non-sinking arrow key layout; a function key on the right side of the space is reduced, leaving a small incisor; the F area is moved to the left to reduce the interval and an extra key is inserted. The keys look a little more coordinated as a whole. The keyboard mode switching switch is designed on the left side of the keyboard, which is also a feature of the Dareu wireless keyboard. The slider switch can be toggled from the side or the front, and there is a strong sense of confirmation when switching. On the right side is the storage slot for the wireless receiver, which has a certain magnetic ability to prevent the receiver from accidentally falling during storage. The Windows/Mac system switching switch and USB-C interface are arranged on the left side of the top of the keyboard. The slot of the USB-C interface is relatively shallow, which has good compatibility with connecting wires, and it is convenient for players to use various USB-C charging cables at hand. Keyboard charging. The keyboard comes standard with a set of two-color injection molding keycaps made of PBT material. The color matching of this set of keycaps uses white letters on a blue background, and blue and white letters on a white background. It feels a bit like a tribute to the Argentine National Team Meaning, after all, the same purple-gold color scheme is a tribute to the Zijin Dynasty-the Los Angeles Lakers. The bottom of the keyboard is flat. There is no height-adjustable feet like ordinary keyboards, but four feet are arranged to ensure the stability of the keyboard when placed. At the same time, some high-gloss textures are also made to decorate the bottom surface to avoid the bottom surface being too monotonous. Dareu A81 three-mode wireless keyboard is also equipped with RGB backlight effect, which can adjust the brightness, color and mode of the light. The frosted and semi-transparent PC positioning board has a certain bonus to the light refraction, and the overall look and feel is still very good. The lighting effect mode is not rich, but it can still meet the needs of most users. The A81 three-mode wireless keyboard is equipped with two switches, the sky switch V3 and the Zijin switch Pro, which are self-developed by Dareu. The sky switch V3 is a light pressure linear switch with a pressure of 40g. It feels softer than the common red switch, and it is close to the TTC gold powder switch. Moreover, the shaft center of the shaft adopts a fence design, which is very stable and does not feel shaking during the pressing process. Of course, if you don’t like the standard switch of Darwin, the full-key hot-swap supported by the keyboard can be compatible with three-pin and five-pin mechanical switches, and you can replace the switch you like by yourself, and match the switch that is more suitable for your needs. body combination. Now many players are beginning to care about the sound performance of the keyboard. The A81 three-mode wireless keyboard uses silicone pads and Porom cotton as the bottom padding, which eliminates the gap inside the keyboard. There is no cavity noise when typing on the keyboard, which is very good. The original percussion sound of the keycap and the shaft body is eliminated. The adjustment of the large keys of the keyboard is in place. The space bar and the Shift key will not feel fleshy when pressed. The consistency is good and there is no steel wire sound. The handling of this large key is quite good. Combined with the feel of the switch body, large keys and sound performance, the A81 equipped with Sky Switch V3 feels consistent and soft, the overall rebound is comfortable, and the sound is pure and clean. Of course, this keyboard is not perfect. Personally, I think the most regrettable thing is that the height of the lower edge of the keyboard has reached as much as 2cm, which is quite high in the current mechanical keyboard. For those who are used to ordinary height keyboards like me For friends, you may need to use it with a hand rest to get the best experience. Furthermore, the keyboard does not have a height-adjustable foot support, which cannot satisfy different players' choice of keyboard height. If it is designed with foot supports, it can alleviate the situation that the lower edge of the lower keyboard is too high. If it is because of the mold that the feet cannot be arranged, it is suggested that Dareu can design magnetic suction feet to solve the problem in the follow-up products. For those who dislike the article too long and don’t read it until the end: Dareu A81 three-mode wireless keyboard uses 75 configurations, and supports three-mode wireless with a battery life of up to 45 days. The arm Gasket structure and large key position adjustment make the keyboard have an excellent feel. Of course, if you are pursuing a more extreme soft elastic feel and don’t care about hot swapping, you can also look at the Dareu A81 wired version without steel structure. In general, the Dareu A81 series uses the Gasket structure of the elastic arm to bring a very soft and elastic feel performance. At the same time, the price is also very conscientious. The starting price of 499 yuan has a good price/performance ratio, which is worth trying. Friends of the Gasket structure start to experience.

Speaking of the 98-key position in the mechanical keyboard, I believe many friends are familiar with it. Although many manufacturers have placed the center of the keyboard arrangement on the 75-arrangement in 22 years, for players who like to use the small keyboard to input numbers, it is even more important. The compact 98-key position is obviously more friendly, and its size is smaller than the conventional 104-key arrangement. At the same time, both the F area and the small keypad area for digital input are fully functional. After Dareu launched the A98 and A98 PRO keyboards that received a very good response, in order to further lower the entry threshold for everyone to choose, they also launched the A98 Youth Edition. When you see the youth version, everyone may immediately think whether this is a poor simplified version. How does Dareu treat the concept of the youth version? Let me take a look. The packaging still adopts Dareu’s recent silver style, and there are not many accessories, but there are still dual-purpose steel wire key pullers, shaft pullers, type-c interface data cables, and a keyboard dust cover. Dareu has launched a lot of new color schemes for this youth version, such as the tiramisu in my hand. I really want to "try" the first time I see it. I can't resist desserts. I also really like the color scheme of this keyboard. The shell and the main letter area of ​​the keycaps are all made of milky white, which is very similar to the cake part of tiramisu. The large key uses the cocoa powder color of tiramisu. At the same time, the ESC and ENTER buttons are all used The orange-yellow color scheme is used for embellishment, and the visual effect is very good. Looking at it directly from the front, in fact, compared with the A98, the A98 Youth Edition only has one less battery display screen, and the others do not. However, the A98 Youth Edition has a slightly missing axis compared to the A98 PRO, but I It doesn't feel like a big problem. On both sides of the keyboard, there are 3-mode switches and storage compartments for 2.4G receivers, which are very ingenious in design. 2.4G and Bluetooth dual wireless connections allow you to connect multiple devices at the same time and switch inputs at any time. In terms of the switch body of the keyboard, Dareu A98 Youth Edition did not use the previously praised sky switch, but replaced it with its own dream switch and firefly switch. I believe everyone should still have an impression of the previous dream color matching. The overall switch White and purple color, POM axis, short spring design, 40gf trigger pressure, 4.0mm total trigger stroke, linear feel, built-in dust-proof wall design, axis stability is quite good, and the use feels smooth. At the same time, Dareu A98 Youth Edition is equipped with the Zijin satellite switch that was well received before, which improves the feel of the large keys a lot. The consistency and the smoothness of the rebound are quite good, which is quite a good "reverse upgrade". "Are. All keys of the keyboard support hot-swappable design. When the shaft body is removed, it can be seen that the keyboard is not filled with padding under the shaft, but the inside of the slotted positioning plate is also filled with a new sound-absorbing rubber structure, and the space slot is also filled. The filling is full, and the cavity sound in the space is well suppressed. When used, the sound is more pleasant. The keycap part adopts the MAD height design this time, the design texture of the dotted cap, the height and the enlarged contact area make the user more comfortable to use. At the same time, the two-color process of the two-color PBT is very good for the keycap treatment. , This set of keycaps is really excellent. Compared with other "Volume King" keyboards at the same price, these are intangible costs. The upper cover of the keyboard is all connected by buckles, and it is very simple to open. The A98 Youth Edition is still a standard Gasket structure design. A silicone sleeve is added to the small ears of the positioning board to provide deformation of the positioning board. The position of the original small screen can also be seen, and the design of the small screen is still reserved, after all, it is the youth version. The antenna position of the A98 Youth Edition is designed on the side close to the user, which is very interesting. At the same time, you can see the sandwich layer between the positioning board and the PCB. This time, it is filled with EPDM rubber, which has both soft elasticity and toughness. This kind of material is harder than Poron material, but it can also provide Gasket deformation and ensure a good soft bounce and consistency of the keyboard. The charging interface of the keyboard adopts the way of separating the small boards, so as not to affect the gasket structure of the keyboard, and the stability when it is deformed. At the same time, two 2000mAh batteries provide power for the keyboard, which brings the use of 6 days with the lights on and about a month without the lights. The performance of time and battery life is quite excellent, and the bottom of the keyboard is still filled with a specially customized silicone pad. Although the sound performance will be very good after it is fully filled, it also slightly limits the deformation of the keyboard. The slotted structure that can be seen everywhere on the PC positioning board guarantees the soft elastic feel, and also reserves holes for the prompt LED lights of the keyboard. Although RGB lighting is used, the lighting effect of the overall keyboard is still slightly weak because the switch body does not use a transparent upper cover, and the keycaps are also designed to be opaque, and for the sake of wireless battery life. There are a variety of built-in lighting effects, and the keyboard can also be replaced without driving. However, if you don’t need the background light for normal use, it is recommended to turn off the light to ensure battery life. Although the name is A98 Youth Edition, but overall, it doesn’t feel much inferior to its own A98. Although some compromises have been made on the sandwich cotton and the small screen, the price of the A98 has been directly pulled to the price of 499. Under the premise of ensuring the excellent hand feel, the three-mode wireless connection, 4000mAh battery life, and the new keycap with a better look and feel design make Dareu A98 Youth Edition a very good choice at this price. Compared with some other volume king keyboards at this price, Dareu’s market-proven stable quality, excellent workmanship, mature and stable after-sales service, these hidden costs that ordinary users can’t see, are the high-value products that everyone chooses in normal times. Points that you may not notice when you are looking for a cost-effective keyboard, and these are precisely what the Roller King keyboard cannot provide. Of course, I hope that everyone in the peripheral market can compete better and bring more and more interesting products to everyone.

For people who need to work on a computer every day, especially those like me who work on a laptop every day, nothing can improve happiness more than a stylish and easy-to-use keyboard. In the busy work, typing on a favorite keyboard, with the clicking sound of the keyboard, the work becomes easier. After get off work, when playing games with friends, a keyboard that can be operated precisely and does not break down can also make the game more handy. Today, I would like to recommend my new favorite——A98 water-permeable three-mode mechanical keyboard. The earliest mass-produced customized products, Gasket structure, word-of-mouth and strength coexist The Gasket structure is the most popular keyboard structure in the past two years. Unlike traditional keyboards, its keyboard is connected by precise extrusion of the upper and lower covers. The inner tank structure has no rigid structure and screw support, and the feel is more moist and even. It does not produce some disturbing noise like traditional mechanical keyboards, so it is well received and sought after by many customized players. In this regard, Dareu A98 is the industry’s first mass-produced Gasket structure mechanical keyboard. Among the several series currently on the market, no matter it is fashionable shape or actual use experience, all of them are loved and respected by users. In the field of mechanical keyboards Its reputation and strength are obvious to all. PC material transparent keycap, crystal clear, creating a different sense of fashion The first time I got it, I was amazed. Even my friends couldn't help but praise: "It's so beautiful!" The keyboard of Dareu uses transparent PC material keycaps, which can be seen clearly. As for the internal structure of the keyboard, in order not to be too smooth, there is a layer of frosted material on the surface, which will not leave fingerprints and increase the comfort of the touch. It will not look greasy after a long time. Under the perfect lighting effect of full-color RGB, the color is gorgeous and the atmosphere is full. It has the soft beauty of women and the rigid beauty of a mechanical keyboard. It is a super easy-to-use desk item. Sky axis V3 spool body, stable structure, bring better user experience In terms of the shaft body, this Dareu A98 water-permeable version adopts the sky shaft V3 structure, straight up and down linear feel + high-density gold-plated spring; coupled with the big key of the purple gold satellite shaft, not only the structure is stable, but also not fleshy. It won't shake, giving people a solid and heavy feeling. The newly upgraded EPDM rubber and high-toughness silicone filling together with the fence-style Gasket structure eliminates noise while increasing the soft elastic feel. My personal feeling is that there is a crisp pressing sound. Let's put it this way, when typing, it's like tapping on something that has a certain degree of elasticity, and the rebound is fast and smooth. Whether it's playing games or working, it feels very good. In order to save desktop space, this keyboard adopts a 98% column layout, which perfectly retains the number keypad and is very convenient to use. Three-mode connection, suitable for various life scenarios This Dareu A98 water-permeable version supports 2.4G+Bluetooth 5.1+wired three connection modes, can quickly connect to laptops and desktops and other devices, compatible with WIN, MAC, IOS, Android systems, it is equivalent to daily use, no matter Both wired and wireless are supported. For example, I like to use bluetooth to connect, but my husband is used to using wired, this is equivalent to a keyboard, we both can use it, so it saves money, haha~ Thanks to the 4000mAh lithium battery device, the performance of this keyboard in terms of battery life is also very impressive. If the light is turned off, it is no problem to persist for a month, and it can also meet the battery life of a month when the light is turned on. In addition, the sleep function can also be set in the case of not charging the surface, which is very convenient. Rich SKUs are available, there is always one that suits you! As one of the earliest mass-produced customized brands, in addition to our water-permeable version, Dareu A98 currently has organic armor version, industrial gray, underglaze green, water-permeable version, time white and tiramisu, etc. There are multiple styles to choose from, and anyone can find a mechanical keyboard that suits them according to their preferences. In short, this Dareu A98 water-permeable version not only has the stability of the traditional mechanical keyboard, but also has the rebound and fullness of the Gasket structure. At the same time, the transparent shape and design, which looks like ice cubes, are clean and clear, and it feels both small and fresh, while taking into account the rigidity of the machine. Therefore, whether it is appearance, shape or configuration, this keyboard is very recommended. If you need it, you can start it~

As a male text worker, the use of mechanical keyboards almost runs through my entire work and daily life. The summary of my personal experience is as follows: In order to use small numeric keyboards, I often choose between mechanical keyboards and ordinary keyboards; The keyboard has a smooth and crisp sense of paragraph, but I am worried about affecting my surroundings. At the same time, my entanglement, I met the Rapoo V700DIY 104-key full keyboard under the introduction of a friend. It has complete functions and is suitable for office work. Secondly, it is supported by the fast silver switch of independent innovation. Full-size hot-swappable, customization is popular, and it is also the first 104-key customized mechanical keyboard launched by Rapoo. More playability and convenience, let me find the perfect balance between the use feel and experience, let me introduce him to everyone... 104+5 is fully functional and more playable, and the simple color matching desktop is versatile and has a high value One of the most important reasons for choosing this keyboard is the full keyboard among the rare mechanical keyboards on the market. It not only supports 104 full keys but also supports 5 special keys. It is really worth it to look good and easy to use. The 104-key full keyboard personally thinks it is more in line with the user's operating habits, and the distribution of each functional area is relatively reasonable; the second thing worth mentioning is the four special function keys, which are M mode switching from left to right, between game mode and office mode. seamlessly switch between them; V1 backlight mode switching button, realizes the switching of 28 kinds of built-in backlight effects; V2 is the switching button of the rightmost scroll wheel mode, switches and adjusts the volume and backlight brightness, and can be adjusted by pushing forward and pulling backward. It realizes stepless adjustment, which is very similar to the feeling of DJ playing discs, and the playability and interaction are stronger. Finally, V3 is a mute key similar to shortcut operations. Fully functional and easy to handle dual scenes of office games. Secondly, this Rapoo V700DIY is also outstanding in appearance. The aluminum alloy suspension top cover is matched with the front pure white keycap, and the extremely narrow frame design is matched with the front suspension brand LOGO. texture. No matter what color desktop mouse is, it is very versatile, and it still looks good in any combination. Rapoo's self-developed fast silver-axis key travel is short, rebounds faster and is more silent, 104-key full-key hot-swappable to enjoy DIY fun Rapoo V700DIY is equipped with Rapoo's independent hot-swappable linear fast silver-axis mechanical switch, which is sensitive to start and rebounds strongly. The total stroke is about 4mm, and the trigger stroke is about 1.3. Difference. It is more suitable for use in games.
