Product details

The Keychron K3 QMK (V3) is an ultra-compact mechanical keyboard in a 75% layout with Swiss ISO key configuration. It combines a space-saving design with full functionality, including arrow keys and function row. This model is particularly suitable for users with limited desk space or for mobile work environments.

Thanks to dual-mode connectivity via Bluetooth 5.2 or USB-C, the keyboard can be flexibly connected to various devices – whether it's a laptop, tablet, or desktop PC. It supports macOS, Windows, and Linux, with the appropriate keycaps for both Mac and Windows included in the package. A side switch allows for easy toggling between operating systems.

The keyboard is fully QMK and VIA compatible. Through the Keychron Launcher, users can directly assign all keys, define macros, and customize the layout in their browser – without additional software or manual configuration. This makes the keyboard appealing to advanced users who want to precisely tailor their input devices to their workflows.

The built-in Keychron Low Profile Switches are pre-lubed and available in linear (red) and tactile (brown, banana) variants. Thanks to hot-swap technology, the switches can be replaced at any time without soldering – for example, to adjust the typing feel or switch to different types. Clicky switches are not included but can be easily added later.

The keycaps are made of ABS plastic in a flat LSA profile and feature translucent legends. This allows for even illumination of the RGB backlighting with over 20 configurable effects.

With its combination of mobility, customizability, and precise typing feel, the Keychron K3 QMK (V3) is particularly suitable for users seeking a portable yet professional keyboard solution – whether for working on the go, programming, or minimalist setups at home.
