75% Gaming Keyboard for Multi-Device Users

The WISDUM Crystal Aurora is a 75% mechanical keyboard built for people who switch between a desktop, a laptop and a tablet. Its compact layout keeps the function row and arrow keys while freeing desk space for mouse movement. The transparent PVC frame and keycaps are designed to showcase the internal RGB lighting.

Tri-Mode Connectivity Changes Daily Workflow

The board connects through 2.4GHz wireless at 1K Hz, Bluetooth 5.0 or a wired link at 8K Hz. Pairing up to three devices lets you move from a Windows XP machine to macOS with a simple FN key combination. No separate receiver juggling or cable swapping is required when you change workstations.

Gasket Mount with Pre-Lubed Linear Switches

A mainstream gasket structure and GravaStar x BSUN custom linear switches come pre-lubed from the factory. The five-layer internal build produces a soft, dampened bottom-out and a crisp sound profile. If you prefer tactile click or heavy actuation force, this linear gasket combination will not match that preference.

Questions about this item

Will the GravaStar x BSUN linear switches need lubrication or replacement after heavy use?

The switches come pre-lubed from the factory and the board is hot-swappable, so individual switches can be replaced without soldering if they ever wear out.

What limits continuous wireless gaming sessions on the 2.4 GHz link?

The 2.4 GHz mode runs at a 1K Hz polling rate, and battery life will be the first practical limit during all-day wireless use.

How warm or loud does the keyboard get when RGB runs at full brightness all day?

The PVC frame and gasket mount keep the chassis cool and the typing sound crisp; no active cooling or fan noise is present.
