Keychron V4 QMK Custom Mechanical Keyboard
- ABS plastic housing
- The keyboard PCB, screw-in stabs, and the steel plate
- Double-shot OSA PBT keycaps (including Mac & Windows keycaps)
- Keychron K Pro switches
The V4 is a fully customizable mechanical keyboard suitable for different scenarios. It’s an entry-level custom keyboard with a mini 60% layout, QMK/VIA support, an acoustic silicone pad, and double-shot PBT keycaps to provide you with a great typing feel and endless possibilities.

All-Around Customizable Keyboard
To build a fully customizable keyboard, we designed every component to be easily assembled so you can customize and adjust any or every part the way you want.
Note: The screw heads are molded into the case, so they have a very strong grip and won’t fall out.
An Epic Core Inside The Keyboard
A powerful ultra-low-power ARM architecture MCU equipped with 128K Flash will provide more flexibility for developers. The polling rate is 1000 Hz out of the box, which makes latency non-existent for the competitive game.
OSA Profile Double-shot PBT Keycaps
These double-shot PBT keycaps have a similar height to the OEM profile and has an SA-like shape. We named it the OSA (OEM spherical angled) keycap. The PBT keycaps will provide excellent oil resistance, enhance the type feel, and prevent the legends from fading out.
Switch Layouts Between macOS & Windows
Built with the Mac users’ experience in mind while still retaining compatibility for Windows devices, the Keychron V4 comes with a system toggle and an additional set of customized keycaps for both Windows and macOS systems. You can now save two different layouts on the keyboard, one for each system.
Program V4 with QMK & VIA
With full QMK and VIA support, you can easily program and remap each key on the keyboard. The open-source firmware means endless possibilities for keyboard layouts, shortcuts, backlight effects, and more.
Get the V4 keymap working on VIA
Since the VIA code for the V4 is still awaiting approval from Github, it is not yet automatically recognized, so you will need to manually download and import the V4 keymap.
To get started, please follow the steps: Download the appropriate kemap JSON file below, open VIA, turn on "Show Design tab" on "Settings" tab, drag the JSON file into the “Design” tab on VIA to get the V4 keymap working on VIA.

The hot-swappable sockets are mounted on the PCB, so you can install or change the switches without soldering. The PCB supports both 3-pin and 5-pin MX mechanical switches.
South-facing RGB LED Lights
The south-facing RGB LED is designed to better illuminate the keyboard backlight from the typist’s angle with the premium non-shine-through PBT keycaps installed. The south-facing RGB is also free from interference when the users install OEM or Cherry-profile alternative keycaps on the keyboard.
Pre-lubed Keychron K Pro Switch
By optimizing the switch mold, the K Pro switch wobbles less than a standard mechanical switch and feels smoother on each hit. Plus, the factory pre-lubed process on all the K Pro switches (exclude the clicky ones), no doubt this will ensure the best smoothness at your fingertips when typing.
All New Screw-In PCB Stabilizers
The screw-in design increases stability and makes it easier for changes and upgrades. Precise craftsmanship makes the stabilizers more stable and less shaky. The big keys’ (space bar, shift, enter, backspace) typing experience is now more stable and smooth. The Keychron V4 also supports third-party screw-in PCB stabilizers.
