Transparent 75% Gasket Keyboard

The Grava Star keyboard uses a compact 75% layout with a transparent black PVC frame that shows internal components and RGB lighting. A gasket mount structure and pre-lubed linear switches deliver a soft, cushioned feel suited to extended gaming or typing sessions. Hot-swappable sockets let owners change switches without soldering.

Tri-Mode Wireless Connectivity Limits

The board connects through 2.4 GHz wireless at 1K Hz polling, Bluetooth 5.0, or wired USB at 8K Hz polling. It pairs with up to three devices simultaneously and switches between them via FN key combinations. Compatibility spans Windows XP through Windows 11 and MacOS, but no other operating systems are supported.

Hot-Swap Installation and Common Issues

Switches pull out and press in without tools, making customisation straightforward for first-time builders. The main risk is bent switch pins or misaligned sockets if excessive force is used. Software control requires the GravaStar Control Center on Windows; MacOS users cannot adjust RGB brightness, speed or colour through the app.

Questions about this item

Should I pick the 75% layout over a full-size board?

The 75% layout keeps the function row and arrow keys while saving desk space, so you still have F-keys for shortcuts without the numpad width.

What does the 1K Hz wireless polling rate mean in daily use?

At 1K Hz the 2.4 GHz link reports key presses every millisecond, giving responsive input for gaming while staying cable-free.

How does Bluetooth 5.0 affect multi-device switching?

Bluetooth 5.0 lets the keyboard pair with up to three devices and swap between them using the FN key combo alongside the 2.4 GHz and wired modes.
