Keychron Q9 QMK Fully Assembled Black Gateron G Pro Red Switches (Knob Version)
The Keychron Q9 is the ultimate tool for minimalists and enthusiasts who demand efficiency. As a 40% ultra-compact mechanical keyboard, it removes the number row and extra function keys to provide a tiny footprint that maximizes desk space and portability. Despite its small size, it makes no compromises on build quality, featuring a full CNC-machined 6063 aluminum body and a double-gasket mount design for a premium, cushioned typing feel.
This Fully Assembled version comes ready to use out of the box in the Carbon Black colorway. It is equipped with Gateron G Pro Red linear switches, which offer a smooth, quiet, and lightweight typing experience perfect for rapid inputs. The keycaps are double-shot PBT in the unique OSA profile (OEM height with spherical shape), ensuring durability and excellent fingertip comfort. With full QMK/VIA support, you can easily program the layers needed to access numbers and symbols on this compact layout.
Key Features
-
40% Ultra-Compact Layout: A unique mini layout that brings the mouse closer to your hands. It reduces arm extension and improves ergonomics for long working sessions.
