Compact 75% wireless gaming keyboard

The WISDUM Halo75 V2 is a 75% mechanical keyboard built around an aluminium top shell and 83 hot-swappable switches. It targets gamers and multi-device users who want a compact layout with per-key RGB and open-source QMK/VIA firmware for deep remapping and lighting control.

Battery life and 1000 Hz polling

A 4000 mAh battery delivers between 9 and 91 hours with all lighting active, 140 to 200 hours with only homing bars lit, and up to 307 hours with lights off. Both wired USB-C and 2.4 GHz wireless modes run at a 1000 Hz polling rate for low-latency input.

Aluminium frame and tri-mode connectivity

The aluminium top case adds rigidity while bottom surround lighting enhances desk presence. Bluetooth, 2.4 GHz and USB-C links let the keyboard pair with up to four devices across Windows, macOS, Linux, Android and iOS, switching instantly without re-pairing. Not suited for users who need a dedicated numpad or prefer a full-size layout.

Questions about this item

How do I install the 2.4 GHz wireless dongle and what step is often missed?

Plug the USB-C dongle into the host, toggle the keyboard to 2.4 GHz mode, then press the pairing key combination; the step often missed is holding the pairing keys long enough for the LED to confirm the link.

What part will need replacement first on the Raspberry 46gf switches?

The hot-swappable switch sockets let you pull and replace individual Raspberry 46gf switches when they degrade, so only the worn switch needs swapping, not the whole board.

At what battery level does the 1000 Hz polling rate drop under sustained RGB use?

The 1000 Hz rate holds until the 4000 mAh pack falls below the threshold that powers the radio; with all lights on the tested window is 9 to 91 hours before the rate can throttle.
