Compact 75% Layout with Screen & Knob

The YUNZII B75 PRO MAX is a 75 percent wireless mechanical keyboard with 81 keys, a customizable screen and a multi-function rotary knob. It uses a gasket-mount structure and comes with double-shot PBT Cherry profile keycaps in a black colourway. The board supports QMK and VIA open-source firmware for full key remapping, macro creation and RGB control.

Tri-Mode Connectivity for Multi-Device Users

Suits users who want one keyboard across up to five devices via Bluetooth, 2.4 GHz wireless or wired USB Type-C. The hot-swappable PCB accepts three-pin or five-pin linear switches and ships with pre-lubed Candy linear switches for a smooth, thocky feel. Not for buyers who need a dedicated numpad, a palm rest or a fixed switch soldered board.

8000 mAh Battery and Hot-Swap Headroom

The 8000 mAh lithium-ion battery delivers extended wireless use between charges. Hot-swap sockets let you change linear switches without soldering, while QMK/VIA lets you reprogram the knob and every key. Heavy typists who prefer tactile or clicky switches will need to supply their own, and the fixed 75 percent layout cannot be expanded to full size.

Questions about this item

What operating system is required for the QMK/VIA customisation on this B75 PRO MAX?

QMK and VIA run in the browser, so Windows, macOS or Linux can all configure the keyboard without extra drivers.

Can the 2.4 GHz wireless dongle stay plugged into a desktop while I pair the same keyboard to a laptop over Bluetooth?

Yes — the keyboard stores up to five paired devices and switches between the 2.4 GHz dongle, Bluetooth channels and the wired USB-C link.

How do I confirm the 8000 mAh battery is charging after I connect the USB-C cable?

The built-in screen shows a charging animation and the current battery percentage while the cable is attached.
