A Refined Piece of Metal Art
The entire metal body is crafted with 6063 aluminum that is processed through CNC machined, polished, anodized, sandblasted, and undergoes 24 more manufacturing stages to make this solid metal piece of art that is the Q4.
All-around customizable keyboard
To build a fully customizable keyboard, we designed every component easily assembled. Therefore, you can customize and adjust each component you want.
Double Gasket Design
The Double Gasket Design is a new innovative structure in the industry. In addition to the gaskets on the plates, we added silicone pads between the top and bottom cases to significantly reduce the sound resonance between the metals and reduce the noise of the impacted metals. This design allows the keyboard to maintain the flexibility of the gasket structure and improves the overall typing sound.
An Epic Core Inside The Keyboard
A brand new ultra-low-power MCU Arm structure that is powerful and armed with 128K Flash to provide more flexibility for developers. The polling rate is up to 1000 Hz out of the box, which makes latency non-existent for the competitive game.
Switch layouts between macOS & Windows
Built with the Mac users’ experience in mind while still retaining compatibility for Windows devices, the Keychron Q4 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.
OSA Profile ABS Backlight Shine-Through Keycaps
To further leverage your typing experience, the Q4 ISO version comes with our unique OSA profile (OEM profile with spherical angle) and ABS backlight shine-through keycaps that aim to provide a more comfortable fingertip feel and a fantastic backlight shine-through effect.
Program Q4 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, even the knob, and more.
Get the Q4 keymap working on VIA
To get started, please follow the steps: download the appropriate keymap JSON file below, open VIA, turn on "Show Design tab" on "Settings" tab, and drag the JSON file into the “Design” tab on VIA to get the Q4 keymap working on VIA.
Since the VIA code for the Q4 is still awaiting approval from Github, it is not yet automatically recognized, you will need to manually download and enter the Q4 keymap.
Note: Only the right JSON file can be input, please find the right version keymap JSON file which matches your keyboard to download.
Q4 Keymap JSON Files
Note: If the VIA software still does not detect your keyboard after you upload the latest JSON file above, please update your keyboard with the latest firmware here. The VIA software will only pair with your keyboard when the JSON file corresponds with the right firmware version.
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.
Note: The Q4's top case has sharper corners to make it much more compatible with third-party keycaps.
Pre-lubed Gateron G Pro Switch
The optimized molded switch with more precise positioning and less wobble will undoubtedly improve the feel at your fingertips. With the fully assembled Q4 version fitted with factory pre-lubricated Gateron G Pro switches, a smoother travel experience is guaranteed for you.
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, delete) typing experience is now more stable and smooth. The Keychron Q4 also supports third-party stabilizers, including Cherry or Durock.
