After the MX Slice36, MReavley published Rzr36, a BLE Choc version of the original.

Modified my Slice36 layout for choc switches, and using a Xiao BLE with ZMK. A 100mAh battery under the top cover on each side is used. USB and power switches at the top – MReavley

Specs

  • 36 keys (3x5+3)
  • Choc, hotswap or soldered
  • Seeediuno Xiao BLE controllers
  • reversible PCB
  • kick-ass case design

The layout has inherited the design cues from the Slice36, but has been modified to take advantage of the more compact nature of the Chocs.

As before, a single PCB is used for left and right, with the only caveat being installing the left controller upside down.

Designing a case that does not increase the height of the keyboard very much is always tricky:

Yeah, that's been one of the things I've liked about not having cases for the Slice derived keyboards, but I did ultimately decide that staring at exposed lipo batteries at my desk everyday wasn't ideal, so I figured I had to cover them – MReavley.

Exploded view of the different layers: the red inside the top cover is also a separate piece glued in/secured with blu-tak, using 3 M3x8 and 3 M3x12mm countersunk bolts.
