PC Hardware and Peripherals Chapter 207: Open the book? Comments on the dismantling of the new structure of the small bug GK75 kit at the price of 200 yuan

What is the end of playing with mechanical keyboards? I personally feel that it is customized. After all, after you have played with dozens of mechanical keyboards with different axes and different brands, you have already had the experience of disassembling and assembling the keyboard. You will want to experience the fun of assembling the keyboard yourself. In terms of experience, it is more convenient to experience different shafts and keycaps.

In the past few years, the price of many customized keyboard kits was relatively high, especially the wireless multi-mode customized kits often cost several thousand yuan, which led to high purchase costs for players, directly dissuading many players. Later, as more and more brands entered the customized keyboard market, the price of wireless multi-mode customized kits has overwhelmed the price of less than 300 yuan or even 200 yuan, but there are some 200 yuan priced. The hardware settings and functions of the customized kit are mediocre, and it can only be regarded as an ordinary shaft tester. Although 200 yuan is not too much, it is better not to buy a tasteless customized kit for me.

There are also many options for wireless multi-mode customized kits at the price of 200 yuan. This is a good thing and a bad thing for me. The reason is that the wider range of options also increases the difficulty of selection, and I am not too I am willing to try some brands that I have never experienced before. I finally chose the GK75 wireless multi-mode customization kit. First, I have already started with the switch body and wireless multi-mode keyboard of Derrick, and the Lite Gasket flick structure. The experience is good, the Bluetooth low-latency is indeed relatively low, and it supports on-board custom functions of the driver. Shafts and keycaps also support the replacement of positioning board accessories of different materials, support the replacement of knob modules and split space positioning board modules, etc.; third, the crazy kit festival of the little nerds brought good prices, which is more suitable for my thinking. Players who want to be early adopters and those who care about price and care about hardware configuration and features.

The items in the package of the small bug GK75 wireless multi-mode customization kit include 1 kit and 1 dust cover. This kit can be regarded as a GK75 multi-mode wireless mechanical keyboard without shafts and keycaps.

In addition, a USB A-C cable and a USB A-C converter are provided, which can meet the needs of different interfaces with different devices at the same time. The wire is designed with a more wear-resistant braided fiber, and both ends are gold-plated to improve service life, oxidation resistance, and signal transmission stability.

The GK75 wireless multi-mode customization kit weighs 797 grams. The outer shell adopts a black translucent design with matte process. We can vaguely see the internal structure, which has a more mechanical feel.

The GK75 wireless multi-mode customization kit uses five anti-skid pads on the bottom to improve the anti-skid effect. It is worth mentioning that the bottom is designed with a wire groove, which is more convenient for players to route. The GK75 wireless multi-mode customization kit adopts a large and small double foot support design, which can achieve two different height adjustments, and each foot support is also designed with a non-slip mat.

The GK75 wireless multi-mode customization kit supports wired connection mode, 2.4G wireless mode and Bluetooth mode. The corresponding toggle switch is designed at the bottom, and there is also a toggle switch to switch between Windows and Mac modes. , to meet the needs of players to connect two devices with different operating systems.

The groove designed on the left side of the bottom is more individual, one side is used as a 2.4G receiver storage slot, and one side is designed with a Type-C interface.

The design of the Type-C interface of the GK75 Wireless Multi-mode Customization Kit, combined with the design of the wire slot, can make the wire connection more secure.

Next, let me disassemble the GK75 wireless multi-mode customization kit. The disassembly is very simple, and even beginners can easily get started. Let’s talk about the space bar first. The kit comes with a standard space bar positioning plate, which can be removed by yourself.

The space bar of GK75 wireless multi-mode customization kit has a unique patented design, which adopts the split space-long space interchangeable module design, which needs to be installed and used with the corresponding positioning board of the original factory, so that the standard space bar can be used. One is divided into three, which is equivalent to two extra buttons. The picture below is the effect picture after the split space is installed.

The design of the split space module can make the complex operation of combined keys more convenient, and can also realize more customized key operations.

The shell of the GK75 wireless multi-mode customization kit is composed of upper and lower layers, which is the upper part of the shell.

The nerdy GK75 wireless multi-mode customized kit follows the patented design of its own flick version Lite Gasket. As an optimized version of the existing kit GASKET structure, the Lite Gasket is based on the combination of the Lite Gasket silicone pad in the middle and the silicone gasket on the screw. And the innovative structure produced.

The design of the Lite Gasket silicone pad is not only used for noise reduction, but also can bring players a more soft and Q-bomb feel.

The workmanship of the PCB board is solid and clean, and there are text markings corresponding to the buttons under each vacancy, which reduces the difficulty of assembly for players. It should be noted here that the two slots with 4 gold-plated dots in the upper left corner, the two slots with 4PIN gold-plated dots in the upper right corner, and the slots with 4 gold-plated dots on the right can be used to install the knob module, so that Realize the interchangeability of the knob module and the key shaft body, further improving more gameplay.

The main control adopts an upgraded version of Weltrend WT59F164, which is a 32-bit MCU with a maximum frequency of 24MHz.

NORDIC N52810 is a low-power Bluetooth (BLE 5.0) module, which has the advantages of supporting high transmission rate, enhanced broadcast packet expansion, smaller size, lower energy consumption, and lower latency.

In terms of battery life, the GK75 wireless multi-mode customization kit has a built-in 4000mAh rechargeable lithium battery. The sound-absorbing cotton design is added above the battery and on the inside bottom to further reduce key noise.

Next, I will come to the actual experience of installing the shaft and keycap. Installation is a labor-intensive task. When installing the shaft, pay attention to the direction of the metal sheet, and don't be overly superstitious about miracles. As for the switch body, I installed the milk switch, silver switch, bumblebee switch, red switch, and blue switch made by the small nerd here, Jiadalong customized silent red switch and Cherry cherry silent red switch. It can also be installed and used normally.

I installed two knob modules on the GK75 wireless multi-mode customization kit, and only need to designate one of them with the F12 button function through the software. After all, the knob supports pressing, clockwise rotation and counterclockwise rotation. Set several different function keys. The key in the upper right corner is a multi-function media key by default, which can directly use the mute and volume adjustment functions. One thing to remind is that we need to prepare 3 ordinary satellite axes and 1 satellite axis corresponding to the space bar.

For the part of the keycap, you can choose the color according to your own preferences, but you also need to choose according to the arrangement of the wireless multi-mode customization kit of the small bug GK75. What I am matching here is the existing idle keycaps for installation.

The matching of keycaps in a variety of colors can make the keyboard look less monotonous. You can combine them according to your own preferences and keycaps. Personally, I suggest that you can start with four or five sets of keycaps for backup.

The following is the rendering of the actual installation. The more keycap sets, the more diverse the effects that can be combined, and the higher the playability.

键帽这方面，我个人建议一是选购一套对应MAC&WIN字符的键帽，比如Ctrl/control、Win/option、ALTcommand等等键帽，毕竟小呆虫GK75无线多模客制化套件支持双系统，日常使用更加方便。二是选购带蓝牙、2.4G标识的键帽，其中数字1对于蓝牙设备1，数字2对应蓝牙设备2，数字3对应2.4G模式。

If you don't have enough hot-swappable switches and keycaps, and you are worried about the incompatibility of the purchased switches and keycaps with the kit, but you want to experience the fun of DIY, then you can consider official switches and keycaps.

下面我们来试试按键，避免某些轴体安装异常而导致无法正常输入的问题。我们可以搭配官方软件GK6XPlus进行测试。软件功能简单易上手，通过软件我们还可以对灯光模式、宏录制功能、自定义快捷键与按键功能等进行设置，也可以进行固件升级，此外软件支持windows& mac双系统全键热插拔全键宏设置，也可以直接免费下载多个内置的主流游戏宏。

In general, this open-book GK75 wireless multi-mode customization kit has RGB lighting, wireless multi-mode, hot-swappable support, and a built-in Nordic low-latency anti-jamming chipset. Compared with similar products The characteristic design is Lite Gasket, multi-knob modules, split space and other accessory systems that support personalized modification. Through relatively high hardware configuration, rich functions, high playability and low price, it enters the kit market and attracts It has attracted the attention of more players, especially for those players who care about the price but want to experience the fun of the kit, as well as players like themselves who want to use idle hot-swappable switches and keycaps.

As for the shortcomings, I personally feel that the mode switch button designed at the bottom is a little inconvenient to operate. It would be better to consider designing it on the side, or directly supporting the combination keys to quickly switch between different modes. In addition, it is recommended that the corresponding satellite axis accessories be provided in the package or pre-installed directly on the keyboard to make it more convenient for players.
