75% Tri-Mode Mechanical Keyboard

The WISDUM Mercury K1 Lite is a compact 75% mechanical keyboard built for gamers and typists who want a transparent, lightweight frame without a full-size footprint. It uses GravaStar x BSUN linear switches with a 40gf actuation force and 3.6mm total travel for responsive input. Tri-mode connectivity covers 2.4GHz wireless, Bluetooth 5.0 and wired USB, letting you pair up to three devices. The 4000mAh battery supports extended wireless sessions.

4000mAh Battery and 13 RGB Modes

A 4000mAh rechargeable battery provides long-lasting wireless use, though heavy RGB brightness will reduce runtime between charges. The board offers 13 built-in RGB lighting modes adjustable for brightness, speed and colour through the GravaStar Control Center software. Transparent keycaps and a clear PVC chassis amplify the lighting, but users who prefer a completely dark setup may find the glow intrusive even at minimum settings.

Transparent PVC Frame and Software Control

The skeletal transparent PVC frame keeps weight low while exposing the switch internals, so the board fits cleanly into minimalist or showcase builds. GravaStar Control Center software handles key remapping, macro recording and lighting sync across compatible peripherals. Wired, 2.4GHz and Bluetooth 5.0 links cover most modern desktops and laptops, but the keyboard lacks dedicated media keys and a volume knob, which some workflows require.

Questions about this item

Will the 75% layout and 2.4 GHz wireless work with my older desktop that only has USB-A ports?

The keyboard includes a USB-A 2.4 GHz receiver and a USB-C cable, so it connects to legacy USB-A ports without an adapter while keeping the compact 75% layout.

How do I confirm the GravaStar x BSUN linear switches are registering every keystroke at 40 gf actuation and 3.6 mm travel?

Open the GravaStar Control Center software, enable the key-test view and press each key; it lights up per press, proving the 40 gf / 3.6 mm switches fire correctly.

Does the box contain the 2.4 GHz dongle and USB-C cable, or must I buy them separately?

The package ships with the Mercury K1 Lite keyboard, a USB-A 2.4 GHz receiver, a USB-C charging cable and the user manual — no extra purchase needed.
