Keychron Q4-J3 60% Brown Switch RGB Wired Mechanical Keyboard - Navy Blue

The Q4 is a mini custom all-metal keyboard ideal for a variety of situations and will upgrade your typing experience. With full aluminum CNC machined body, double-gasket design, and QMK/VIA support, the Q4 is the ultimate choice for the mini keyboard.

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 1000 Hz right out of the box, which makes the latency hardly noticeable even in competitive games.

OSA Profile Double-Shot PBT Keycaps:
For the new double-shot PBT keycaps, we built a new profile. It has 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 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.

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, and more.

Hot-Swappable:
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 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.
