Compact 75% Layout

The Redragon AU75 is an 81-key mechanical keyboard that fits the essential keys into a 75 percent form factor. It uses tactile switches with a 3.5 millimetre total travel and a 1.8 millimetre actuation point, and the hot-swappable PCB lets owners change switches without soldering. Per-key RGB lighting offers 16.8 million colours controlled through dedicated FN shortcuts.

Desktop and Mobile Users

The board suits anyone who wants a smaller footprint without losing function keys or a navigation cluster. The multi-function knob handles volume and lighting adjustments, while macro programming supports custom shortcuts for work or play. Buyers who need a dedicated number pad or a full-size layout should look elsewhere.

Tri-Mode Connectivity

A single device can pair with up to five hosts across Bluetooth, 2.4 GHz wireless and USB-C wired modes, switching between them on demand. The integrated 4000 milliampere-hour lithium-ion battery powers extended sessions, and the keyboard recharges over the same USB-C link used for wired operation.
