A small screen beside the knob
The TFT screen has pages for time, battery and connection information, plus uploaded pictures and GIFs. Screen content is customised through YUNZII's web application, not QMK/VIA. Beside it, the rotary knob has a press-to-mute action and can receive a different assignment through QMK/VIA.
81 keys without the number pad
The 75% ANSI layout keeps the function row above the typing area and dedicated arrows at the bottom right. A narrow navigation column sits below the screen. The images show pink, dark and pale blue keycap arrangements; decorative and transparent keycaps are specific to the version pictured.
Change the feel, keep the board
The gasket-mounted assembly includes foam and a silicone dampener beneath the keys. Hot-swap sockets accept compatible 3-pin and 5-pin switches. Candy, Cocoa Cream V2 and Milk V2 linear switches appear in the comparison image; the supplied switch depends on which variant you select.
Wireless options and an 8000 mAh battery
Use three Bluetooth pairing channels to switch between devices, choose the 2.4 GHz receiver, or connect a USB-C cable. The keyboard has Windows and macOS modes. An 8000 mAh battery powers wireless use; screen and backlight settings affect how often you need to recharge.

Frequently asked questions
Does QMK/VIA change the screen images?
No. QMK/VIA handles keyboard and knob customisation. The TFT screen's pictures and GIFs are customised separately through YUNZII's web application.
Does the B75 PRO MAX include a number pad?
No. It uses an 81-key 75% ANSI layout with a function row, dedicated arrows, a screen and a knob.
Are all versions fitted with the same switches and keycaps?
No single configuration should be assumed. The images show Candy, Cocoa Cream V2 and Milk V2 linear switches, plus different keycap treatments. Use the selected variant's colour and switch details.
