Peripheral shooting record Part 66: RK H81 three-mode wireless 75% mechanical keyboard unboxing evaluation

After experiencing the explosion of key layouts such as 60 keys, 68 keys, 84 keys, 96 keys, and 98 keys, 75% of keyboards have become the main key layouts that have attracted attention in the past two years. 75% of the keyboards retain the F area, arrow keys and some function keys in terms of key positions to ensure that the daily use of the keyboard will not be restricted. The small size means that it does not take up too much space on the desktop, and it is also very convenient to carry around. As mass-produced brands begin to carry customized elements such as PC positioning boards, Gasket structures, hot-swappable shafts, noise-absorbing pads, and pads under the shafts, the playability of keyboards is getting higher and higher. RK has recently released a variety of cost-effective keyboards. The newly released H81 three-mode 75% mechanical keyboard is full of configuration, sound and feel. Next, the keyboard will be evaluated out of the box by combining graphics and text.

▲The front of the outer package of RK H81 is printed with information such as the brand logo and the physical picture of the keyboard

▲The switch body used for the keyboard is pasted on the side of the inner box, and the colorful red switch jointly customized by RK and TTC - Evening Star color matching

▲Keyboard accessories include: transparent dust cover*1, Type-C data cable*1, key/shaft puller*1

▲One end of the data cable adopts Type-C to USB design, and the overall black rubber outer covering is moderately soft and hard

▲ RK H81 is equipped with the colorful red switch jointly customized with TTC - Evening Star, wired/Bluetooth 5.0/2.4G wireless three-mode, full key without punching, RGB backlight, Gasket structure, hot-swappable switch, sandwich silicone sound-absorbing cotton, Shaft pad, bottom silencer silicone, PBT keycap and other configurations

▲Evening star color matching keycap is composed of blue, gray and black. The key layout is similar to the common 75% keyboard. However, H81 has a toggle function knob in the upper right corner.

▲The function knob can be toggled to switch between wireless off, 2.4G wireless mode, Bluetooth channel 1, Bluetooth channel 2, and Bluetooth channel 3

▲The Typc-C data interface is easy to plug and unplug, and the scope of application is wider. The left side is the Type-C expansion interface

▲A total of four non-slip foot stickers on the back of the bottom case, the measured anti-slip performance is very good

▲The keyboard is equipped with double-height non-slip feet, which can provide three different heights in total, and users can adjust it according to their usage habits and usage scenarios

▲The magnetic storage compartment on the back can easily organize the 2.4G receiver

▲The English name of RK is printed on the lower right corner of the keyboard: ROYAL KLUDGE

▲The keyboard is equipped with two-color PBT closed character keycaps, and the surface is made of fine frosted texture. It is comfortable and non-slip, and the overall weight is light. The inner space is large, and there will be no problems such as top shaft cover and keycap jamming.

▲This time, the H81 keyboard released a total of three color schemes: Baiye, Ruyin, and Evening Star. The color scheme of the colorful red switches on the three keyboards is also the same as that of the keyboard. Although the colors of the three switch bodies are different, the core data and feel are the same. That is what we often call the skinning axis

▲The core data of the colorful red switch is the same as that of the TTC gold red switch V3. The linear shaft body, 1.9mm trigger stroke, 4.0mm bottoming stroke, 41g triggering pressure, 48g bottoming pressure, the shaft cover and the shaft seat are made of nylon PA material, POM axle, 18.5mm long spring. The shaft and spring have been lubricated before leaving the factory, and the overall feel can be used by hand without relubrication.

▲The keyboard is equipped with a standard 3.5mm thick silicone sound-absorbing pad. The silicone material is heavier than felt and Poron foam, which can make the keyboard have a solid feel and dull sound. It can also increase the weight of the keyboard and improve the overall thickness of the keyboard. A bottom sound-absorbing silicone pad is also added under the PCB to further eliminate the cavity sound generated by hitting the shaft body

▲Adding an assembly shaft underpad above the PCB can further optimize the sound of tapping the shaft body. The keyboard supports hot-swapping of the entire shaft body. It supports three-pin/five-pin shafts.

▲The large key position satellite shaft has been pre-lubricated before leaving the factory. It feels clean and neat. There is no fleshy, stuffy, or steel wire sound in this one. The overall tuning effect is very good, reaching the level of hand use.

Three-mode multi-device support, Gasket structure, PBT two-color keycaps, RGB backlight, TTC shaft body, hot-swappable shaft body, silicone sandwich pad, shaft under pad, bottom silicone noise-absorbing pad, as if this is the full range of mass-produced keyboards at this stage level configuration. Three connection modes enable the keyboard to adapt to more usage scenarios and users. The PBT keycap is durable and oil-resistant. The silicone sandwich pad + shaft bottom pad + silicone bottom pad makes the keyboard feel more solid and the sound is cleaner and dull. The plug-in function makes the keyboard more playable, and the addition of the TTC shaft guarantees the life and feel of the keyboard to a certain extent.
