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 rotary knob. It uses a gasket mount structure and double-shot PBT Cherry profile keycaps in a white colourway. The board is aimed at gamers and productivity users who want a compact form factor with extra media control.

Upgrade from Basic Wireless Boards

This model replaces keyboards that lack a screen, knob or open-source firmware support. The jump is worth it when you need QMK/VIA customisation, tri-mode connectivity for up to five devices and an 8000 mAh battery for long wireless sessions. It is not for buyers who require a full-size layout with dedicated macro column or numeric keypad.

Hot-Swap Install with Tri-Mode Pairing

Hot-swappable sockets let you change linear switches without soldering, while pre-lubed Cocoa V2 switches are ready to use. Connect via USB Type-C wired, 2.4 GHz wireless or Bluetooth and switch between paired devices. The main friction point is learning the QMK/VIA software for deep remapping and screen configuration.

Questions about this item

What desk space does the 334.4 mm by 143.6 mm footprint need?

The 75% keyboard measures 334.4 mm wide and 143.6 mm deep, so allow at least that much clear desk area plus room for the detachable USB Type-C cable when wired.

How do I load a VIA keymap onto the B75 PRO MAX, and which step is often missed?

Connect via USB Type-C, open the VIA web app in a Chromium browser, authorise the device, then flash the JSON keymap; the step users skip is clicking "Authorize device" before loading the file.

When will the 8000 mAh battery need replacing, and how is it accessed?

The internal lithium-ion pack is not user-replaceable; after several hundred charge cycles capacity will drop, at which point the whole unit must be serviced or replaced.
