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 K3 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 K3 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 Light Effect key (located on the K3 Pro’s top right corner) 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.
Get the keymap working on VIA
Since the VIA code for the K3 Pro is still awaiting approval from Github, it is not yet automatically recognized, so you will need to manually download and import the K3 Pro keymap.
Please download the keymap JSON file below. Connect your keyboard and device with the provided cable, and toggle the switch to cable mode. Open VIA, click on the "Show Design tab" on the "Settings" tab, enable "Use V2 definitions (deprecated)" on the "Design" tab, and drag the JSON file into the “Design” tab on VIA to get the K3 Pro keymap working on VIA.

Suitable For All Devices
Offers a Mac layout while still being compatible with Windows, the K3 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, which makes latency non-existent for the competitive game.
Hot-swappable
We all have our unique typing preferences, that’s why we are offering hot-swappable option on the K3 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 K3 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 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).
