YUNZII B75 PRO MAX 75% Wireless Mechanical Gaming Keyboard (Beige, Cocoa V2 Switch)

Compact 75% Layout with Screen & Knob

The YUNZII B75 PRO MAX is a 75 percent mechanical keyboard with 81 keys, a customizable screen and a rotary knob. It uses creamy pre-lubed Cocoa V2 linear switches and double-shot PBT Cherry-profile keycaps. The case is ABS in a beige finish and the board supports QMK/VIA open-source firmware for full remapping and macro creation.

Upgrade from Keyboards Lacking a Screen or QMK/VIA

This model replaces a standard 75 percent board that has no status screen, no knob and no open-source firmware support. The jump is worth it when you want live battery, time and OS indicators on the keyboard itself and the ability to remap every key and the knob without proprietary software. It is not for buyers who need a dedicated numpad or a full-size layout.

Hot-Swap PCB and Tri-Mode Connection

The hot-swappable PCB lets you change switches without soldering, and the board connects via wired USB Type-C, 2.4 GHz wireless or Bluetooth to up to five devices. An 8000 mAh battery powers the wireless modes. Installation is straightforward: plug the receiver, pair Bluetooth or use the cable, then flash QMK/VIA if desired. The main pitfall is forgetting to update the firmware before heavy customisation, which can cause the knob or screen to behave unexpectedly until the latest build is applied.
