Keychron K9 Pro

The Keychron K9 Pro is QMK/VIA wireless custom mechanical keyboard. It has a min 60% layout with an ultra-slim design, providing an epic typing experience and maximizing productivity!

Wireless and Wired

An excellent solution for multitasking. Connects the K9 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.

You can also enjoy a USB Type-C wired connection with 1000 Hz polling rate which is engineered for the competitive game.

Ultra-Slim

The innovative low-profile Gateron switch is 31% slimmer than conventional normal profile switches makes the aluminum body K9 Pro one of the thinnest wireless mechanical keyboards in the world. While still delivering a distinguished tactile response.

Program with QMK & VIA.

QMK/VIA means endless possibilities for a fluid workflow. Thanks to our engineering team, it's the first time in history that a wireless mechanical keyboard has these kinds of capabilities right out of the box.

Simply connect the K9 Pro to your device with a cable, drag and drop your favorite keys or macro commands to remap any key you want on any system (macOS, Windows, or Linux).

Check out the video above demonstrating how to remap the Backspace key to an Eject key with the VIA software, so you can get a shortcut to put your Mac to sleep (Command-Option-Eject), or even remap the fn key in a breeze. It’s never been so intuitive and flexible to personalize your own keymap.

An ultra-low-power ARM Cortex-M4 32-bit STM32L432 MCU which is powerful, and equipped with 128K Flash will provide more flexibility for developers.

Suitable For All Devices

Offers a Mac layout while still being compatible with Windows, the K9 Pro is one of the few on the market that has the same multimedia and function key functions as Apple keyboards for Mac users, but with more tactile feedback.

You can even configure different keymaps for both Mac and Windows devices. While VIA software is compatible with macOS, Windows, and Linux. Includes keycaps for both macOS and Windows (and additional esc and enter keys) to allow you to switch between operating systems with ease.

An Epic Core Inside

A powerful ultra-low-power ARM architecture MCU equipped with 128K Flash will provide more flexibility for developers. The polling rate is 1000 Hz on wired mode right out of the box, which makes the latency hardly noticeable even in competitive games.

Hot-swappable

We all have our unique typing preferences, that’s why we are offering hot-swappable option on the K9 Pro, so you can easily hot-swap every low-profile Gateron mechanical switch in a few seconds to customize the typing experience without soldering.

*The K9 Pro is currently compatible with Gateron low-profile mechanical switches only, as QMK does NOT support low-profile optical switches.

Low-Profile Gateron Switch

The Gateron low-profile MX 2.0 Mechanical switch is designed to enhance reliability. Gateron's reputable switches are your best choice for a precise, smooth, and reliable fingertip feel whether you prefer linear (red), clicky (blue), or something in between (brown).

Low-Profile Double-shot PBT Keycaps

Designed for premium type feeling, the K9 Pro comes with our unique double-shot PBT keycaps that made of durable non-backlight shine through PBT material with excellent oil resistance for long-term use.

Redesigned Stabilizers

We’ve redesigned the stabilizers to make it stay on the level the same way as the switch while making sure it still delivers reliability and less wobble on the big keys like the space bar, left Shift, backspace, and Enter key.

RGB Backlights

Comes with more than 22 types of RGB backlight settings (as well as a static white backlight option), and 14 types of backlight settings on the White Backlight version. You can further fine-tune the RGB hue, saturation, brightness, effect speed with ease.

Ergonomic Support

Three levels of adjustable typing angle aim to provide long-lasting ergonomic wrist support.
