Compact 75% Wireless Mechanical Keyboard

The usbroway GK330 is a 75% gaming keyboard offering three connection modes: USB-C wired, Bluetooth and 2.4 GHz wireless. It supports simultaneous pairing with up to five devices so users can switch between work, gaming and study setups without re-pairing.

Hot-Swappable Switches and 4000mAh Battery

The board uses pre-lubed Reaper switches on a single-key slotted PCB and accepts both 3-pin and 5-pin switches for tool-free changes. A 4000mAh rechargeable battery delivers up to 55 hours of runtime with RGB backlighting active and up to 220 hours with lighting off.

Gasket Mount with Control Knob for Typists

A five-layer gasket mount and silencing fill create a softer, cushioned keystroke feel while a built-in rotary knob gives instant volume control. The compact layout omits a dedicated number pad and function row, so users who rely heavily on those keys should consider a full-size alternative.
