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 Q9.

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 acoustic 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.

OSA Profile Double-shot PBTKeychron Q9 40% Percent Layout Mini Custom Mechanical Keyboard

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 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 Q9 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.

Programmable Knob

Designed to enhance your creative workflow, the premium rotary encoder allows you to easily customize your favorite keys and macros on the knob through the VIA software.

You can easily customize the Q9's knob to your desired key or macro commands such as: zooming in/out, adjusting screen brightness, brush size, volume, selecting video clips or photos, or backlight hue.

Program Q9 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 Q9 Plus keymap working on VIA

Since the VIA code for the Q9 Plus version is still awaiting approval from Github, it is not yet automatically recognized. Please download the 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 Q9 Plus keymap working on VIA.

Note: The Q9 can be automatically recognized now by the VIA, so it doesn't need the keymap downloaded.


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 Q9's top case has sharper corners to make it much more compatible with third-party keycaps.

Pre-lubed Gateron G Pro & Keychron K Pro Switches

By optimizing the switch mold,  these Pro switches wobbles less than the standard mechanical switch and feels smoother on each hit. Plus, the factory pre-lubed switches will ensure the best fingertip smoothness. Not to mention the K Pro banana switch provides an early tactile bump at the top with a uniquely smooth experience like those Panda switches on the market.

Note: The Gateron G Pro Switches are mounted on the Q9 Fully Assembled Version, while the Keychron K Pro Switches are on the Q9 Plus Fully Assembled Version.

All New Screw In PCB Stabilizers of Keychron Custom Mechanical Keyboard

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 Q9 also supports third-party stabilizers, including Cherry or Durock.

ANSI & ISO Layouts

ISO layout is widely used in Europe while the ANSI layout is widely used by the rest of the world.

Note: If you live in Europe, we recommend you purchase the "Barebone ISO” version with the corresponding ISO keycaps. The "Barebone ISO” is suitable for all ISO keyboard countries like the UK, Germany, France, Italy, Spain, Denmark, Norway, Sweden, Finland, Iceland, etc.
