75% mechanical keyboard with knob
YUNZII B75 PRO
The B75 PRO keeps the everyday controls close: a function row, dedicated arrows and a rotary knob in a 75% layout. Turn the knob for volume or switch it to lighting control. A gasket-mounted build, five damping layers and hot-swap sockets give this wireless keyboard plenty of scope for small personal adjustments.

The layers below the keycaps
A gasket structure supports the typing assembly, with five damping layers beneath the keys. The construction diagram includes a PC plate, foam, PET and silicone components. Pre-lubricated stabilisers support the larger keys, while the double-shot PBT keycaps use a sculpted Cherry profile.
Change the feel, keep the layout
Full-key hot-swap sockets let you replace compatible 3-pin or 5-pin mechanical switches without soldering. The 75% arrangement keeps the function row and arrows together with a short navigation column. You can experiment with the switches while leaving those familiar positions in place.
Choose a connection, then set your keys
Use Bluetooth, the 2.4 GHz receiver or USB-C to connect. A 4000 mAh battery handles wireless use, with a keyboard shortcut to check its level. The Windows customisation software covers key assignments, macros and RGB; using the keyboard on macOS is separate from software support.

Frequently asked questions
Can I use it with a Mac?
Yes, for everyday keyboard use. The customisation software is Windows only, so its key-remapping, macro and lighting tools are not confirmed for macOS.
Does this B75 PRO support QMK/VIA?
QMK/VIA support is unverified for this version. Its documented customisation software is a Windows-only driver, so do not choose it on the assumption that it supports QMK/VIA.
Which switches are included?
Check the selected product option for the fitted switches. You can replace them later with compatible 3-pin or 5-pin mechanical switches using the hot-swap sockets.
