Keychron Q4 Pro
Meet the Keychron Q4 Pro, a full-metal QMK/VIA wireless custom mechanical keyboard. Along with our many premium designs, including double-gasket design, PBT keycaps, screw-in stabs, etc., it will deliver you an unprecedented typing experience!
Choose the keycaps, switches, and more accessories for your Q4 Pro.
Wireless and Wired
An excellent solution for multitasking. You can connect the Q4 Pro with up to 3 devices wirelessly via its stable Broadcom Bluetooth 5.1 for seamless multitasking across your laptop, phone, and tablet. Switch among them swiftly, and it’s fully compatible with both Mac and Windows. A reliable USB Type-C wired connection is also available when you need it.
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 Pro.
Easy Assemble
We designed every component to be able to assemble easily so you can customize and adjust each component with ease to create your ultimate typing experience.
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.
Experience the next level of key sounds and comfort with our gasket mount design together with a flexible PC (Polycarbonate) plate. This design combination allows the keyboard to maintain the flexibility of the gasket structure and improves the overall typing sound.
An Epic Core Inside The Keyboard
A powerful ultra-low-power ARM Cortex-M4 32-bit STM32L432 chip (MCU) equipped with 128K Flash will provide more flexibility for developers. The polling rate is 1000 Hz right out of the box on type-c wired mode (90 Hz on wireless mode), which makes the latency hardly noticeable even in competitive games.
KSA Double-Shot PBT Keycaps
To further fine-tune your typing experience, we designed our unique Keychron spherical-angle (KSA profile) double-shot keycap set with premium non-backlight shine through PBT material, that is oil-resistant and durable for long-term use.
Suitable for All Devices
Built with the Mac users’ experience in mind while still retaining compatibility for Windows devices, the Q4 Pro 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 The Q4 Pro with QMK & VIA.
Endless possibilities for a fluid workflow thanks to its ability to remap any key, and create macro commands, shortcuts, or key combinations through the QMK/VIA.
Check out the video above demonstrating how to remap the Right Control key to an Eject key with the VIA software to create a shortcut to put your Mac to sleep (Command-Option-Eject).
Get the Q4 Pro keymap working on VIA
Since the VIA code for the Q4 Pro is still awaiting approval from Github, it is not yet automatically recognized. Please 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 Pro keymap working on VIA.
Hot-Swappable
Every detail matters for a personalized typing experience, that’s why we give you the power. You can hot-swap every switch on the Q4 Pro with almost all of the 3pin and 5pin MX style mechanical switches on the market (including Cherry, Gateron, Kailh, Panda, etc.) without soldering required. You can customize your own typing experience in seconds.
South-Facing RGB
Comes with 22 types of RGB backlight settings. You can further fine-tune the RGB hue, saturation, brightness, effect speed, and different modes, or even remap these keys with QMK/VIA.
Keychron K Pro Mechanical Switch
By optimizing the switch mold, the Q4 Pro switch wobbles less than the standard mechanical switch and feels smoother on each hit. Plus, the factory pre-lubed K Pro switches will ensure the best fingertip smoothness. Not to mention the banana switch provides an early tactile bump at the top with a uniquely smooth experience like those Panda switches on the market.
PCB Stabilizers
No detail is too insignificant when it comes to your fingertip feel. We’ve integrated the PCB-mounted screw-in stabilizers for a smoother typing experience with less wobbliness on the big keys such as the space bar, shift, enter, and delete keys. You can even customize your favorite stabilizers on your own.
