Ideal for beginners
The Keychron K3 QMK Version 3 is made for those who have little space on their desk – or are on the go a lot. It's slim, lightweight, and super compact. With its 75% layout, it offers all the important keys including function keys and arrow pad despite its compact size – ideal for productive work without wasting space. Whether you're working from home, at university or on the go in a coworking space: With this keyboard, you can type comfortably and intuitively. Thanks to Bluetooth 5.2, switching between laptop, tablet and smartphone works without stress – just stay connected. In addition, there is the pleasant typing feel of the flat mechanical switches – not a clack monster, but also not a sloppy notebook character.
For IT professionals & enthusiasts
QMK and VIA are on board – in full. All customizations run directly in the browser via the Keychron Launcher – without any additional software. Whether you build macros, define shortcuts or completely change your layout: everything can be configured live. The available Keychron low-profile switches are pre-lubricated and either linear (red) or tactile (brown, banana). Clicky switches are not included in the scope of delivery, but can be retrofitted at any time thanks to hot-swappability. The change is possible without soldering. The ABS keycaps in the LSA profile have a pleasantly flat surface and translucent legends - perfect for RGB lighting with over 20 effects. Matching keycaps for Mac and Windows are included - including a switch for system switching on the back.
