Yunzii B68 vs B75 Pro MaxQMK/VIA and TFT Screen or Aluminum Case

The Yunzii B68 listing does not mention QMK or VIA support, so remapping relies on the vendor software described for RGB and function customization. The B75 Pro Max explicitly lists QMK/VIA open-source firmware for key remapping, macros, RGB and knob customization. If open-source firmware matters, the B75 Pro Max is the documented option.

The B75 Pro Max lists an 8000mAh battery, while the B68 lists a 5000mAh cell. Both are tri-mode boards with Bluetooth, 2.4 GHz and wired connections, so the larger battery favors the B75 Pro Max for longer wireless use. The B68's 5000mAh capacity still supports extended untethered sessions per its listing.

The B68 is listed with an aluminum case, which is one of its main differentiators. The B75 Pro Max listing does not state an aluminum case. Buyers who want a metal chassis should weigh this in favor of the B68.

The B75 Pro Max screen is listed at 160 x 96px and shows battery level, date and time, operating system, GIFs and photos. The manufacturer also notes the screen supports customization through an online website. The B68 has no screen.

Both use gasket mounts, pre-lubricated linear switches and double-shot PBT keycaps, and both list five-layer dampening. The B75 Pro Max adds precisely tuned stabilizers and a 75% layout with 81 keys, which keeps more keys available. The B68's 65% layout with 66 keys and a knob is more compact if you prefer a smaller board.

Yes, both list full-key hot-swap sockets that accept 3-pin and 5-pin switches. That means you can change switches without soldering on either board. The B75 Pro Max adds QMK/VIA firmware on top of the hardware customization.

The B68 listing states Mac/Windows support, and its vendor page notes compatibility with both Windows and MacOS. The B75 Pro Max page mentions operating system indicators and support for Windows, Mac, Linux and Android alongside extra keycaps for Mac and Windows layouts. Check the specific color and switch variant you order for included keycaps.

The B68 is listed at 700g and the B75 Pro Max at 993g, so the B68 is lighter. The B68 also has a smaller 65% footprint at 326 x 117 x 32mm versus 334.4 x 143.6 x 42.15mm for the B75 Pro Max. Both offer Bluetooth and 2.4 GHz wireless for cable-free use.

Yes, the B75 Pro Max is listed as an 81-key, 1 knob plus TFT screen layout with a multi-function knob defaulting to volume. QMK/VIA lets you customize the rotary knob along with key remapping. The B68 also has a multifunction knob that switches between multimedia and RGB modes with a long press.

Both boards offer YUNZII Milk V2 Linear and Cocoa Cream V2 Linear switches, and the B75 Pro Max adds a YUNZII Candy Linear option. Both listings describe the switches as pre-lubricated linear types. Since both sets are linear, the choice comes down to sound and feel rather than tactile feedback.

Both vendor pages state the keyboards can connect to up to five devices over Bluetooth, 2.4 GHz and wired connections. That makes either board usable across a desktop, laptop and other devices with quick switching. The B75 Pro Max listing explicitly names laptops, Chromebooks, desktops and monitors as examples.

The B75 Pro Max lists QMK/VIA support, a customizable TFT screen via an online website and a remappable knob, which gives it more customization options than the B68. The B68 still offers hot-swap sockets, five-layer dampening and vendor software for RGB and function settings. For firmware-level control, the B75 Pro Max is the documented choice.
