Keychron K1 Max Low-Profile QMK/VIA Brown Switches Wireless Mechanical Keyboard
K1M-H3
The Keychron K1 Max K1M-H3 is designed for users who want the precision and feel of a mechanical keyboard in an ultra-slim, modern form factor. Featuring an 80% tenkeyless layout, it retains dedicated function keys while freeing up valuable desk space for improved ergonomics and mouse movement.
This model comes equipped with hot-swappable Low-Profile Gateron Brown mechanical switches, delivering a tactile bump without the loud click of traditional clicky switches. The hot-swappable PCB allows compatible low-profile Gateron mechanical switches to be replaced without soldering, making future customization quick and easy.
Tri-mode connectivity provides maximum flexibility. The ultra-fast 2.4GHz wireless connection delivers a 1000Hz polling rate for responsive gaming, while Bluetooth 5.1 allows pairing with up to three devices simultaneously. When uninterrupted performance is required, simply connect via the detachable USB Type-C cable.
Powered by open-source QMK firmware and VIA software, every key can be remapped while creating advanced macros, shortcuts, and custom layers. The powerful ARM Cortex-M4 processor provides smooth operation, while the Keychron Launcher offers browser-based configuration without additional software installation.
Built with an aluminium top frame and durable ABS chassis, the K1 Max combines premium construction with excellent portability. Low-profile double-shot PBT keycaps resist shine and wear, while RGB backlighting offers more than 22 lighting effects with adjustable colours, brightness, and animation speed. The rechargeable 2000mAh battery provides long-lasting wireless performance for work or gaming.
