Compact 75% Layout with Screen & Knob

The YUNZII B75 PRO MAX is a 75 percent mechanical gaming keyboard with 81 keys, a built-in screen and a rotary knob. It uses ABS construction and double-shot PBT Cherry-profile keycaps in black with beige and white accents. Connectivity covers wired USB Type-C, 2.4 GHz wireless and Bluetooth for up to five devices.

QMK/VIA Customisation for Tweakers

Suits enthusiasts who want open-source firmware control over key mapping, macros, RGB lighting and knob behaviour across multiple profiles. Not for buyers who need a dedicated number pad, a full-size layout or a keyboard without battery maintenance.

Hot-Swap Sockets and Tri-Mode Pairing

Hot-swappable sockets let you change linear switches without soldering; the board ships with pre-lubed Milk V2 switches. Pairing over 2.4 GHz or Bluetooth is straightforward, though switching between five paired devices can require a learning period. The 8000 mAh battery charges via USB Type-C.

Questions about this item

What operating system must my computer run to use the QMK/VIA customization on this keyboard?

The keyboard supports both Windows and Mac, so either OS can run the QMK/VIA configurator for remapping keys and macros.

Can I keep my existing USB-A cable and still connect the B75 PRO MAX in wired mode?

The board only accepts a USB Type-C cable for wired use, so a USB-A cable would need a Type-C adapter or replacement.

How do I confirm the 8000mAh battery is charging after I plug in the Type-C cable?

The built-in screen displays the battery level in real time, so you can watch the percentage rise while the cable is connected.
