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.

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.
