Compact 75% Layout with Screen & Knob

The YUNZII B75 PRO MAX is a 75 percent mechanical gaming keyboard with 81 keys, a customisable display and a multi-function rotary knob. It uses a gasket-mount structure and comes fitted with pre-lubed linear switches and double-shot PBT Cherry-profile keycaps. The aluminium-alloy case measures 334.4 by 143.6 by 42.15 mm and weighs approximately 1.66 kg. Tri-mode connectivity covers wired USB-C, 2.4 GHz wireless and Bluetooth for up to five paired devices.

Suited for Customisers; Not for Minimalists

Enthusiasts who want QMK or VIA firmware control, per-key RGB tuning and hot-swap switch flexibility will appreciate the open software stack and creamy linear feel. The 8000 mAh battery supports long wireless sessions across Windows and macOS. Buyers who need a dedicated numpad, macro column or wrist rest should look elsewhere, as the compact layout omits those elements entirely.

Straightforward Setup with Hot-Swap Flexibility

Plug the USB-C cable, pair via 2.4 GHz dongle or Bluetooth, then launch the VIA web configurator to remap keys, macros and knob behaviour without flashing firmware. Hot-swap sockets let you swap linear switches for tactile or clicky variants in seconds. The main friction point is the initial VIA learning curve for users unfamiliar with JSON keymaps or layer logic.

Questions about this item

Does the YUNZII B75 PRO MAX need any extra hardware for its three connection modes?

The keyboard includes a USB Type-C cable for wired use, a 2.4 GHz receiver for wireless, and built-in Bluetooth for up to five devices — no other hardware is required.

Will the 75% layout and gasket mount feel different from a standard full-size board I might keep?

The compact 75% layout has 81 keys and a rotary knob, while the gasket mount and pre-lubed linear switches give a softer, deeper sound profile than typical full-size designs.

How can I confirm the keyboard is working correctly after I set it up?

The built-in screen shows battery level, date, time, active operating system and connection mode, so you can verify power, pairing and layout switching at a glance.
