I chose to build a Cantor (https://github.com/diepala/cantor) partially because I liked the diodeless design, the thumb cluster that is a bit splayed out and I didn’t want to commit to a 3x5 layout like in the cheapino. I pretty happy with it.

Did you modify the PCB to accommodate the new microcontroller?

Honestly, it is kinda neat. Just gotta be careful if you are carrying it around. What sort of case are you using, did it come with those tenting screws?
