Rzr36
MReavley's split Rzr36 is the BLE Choc version of his earlier Slice36.
Published April 11, 2024
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.
