What are the best designs to cheap out? E.g. Reviung34 only needs 1 controller.

• CrowBoard

  6 42 1.7

  Single Board 34/36 Keyboard

I’m really digging the crowboard by Doesntfazer (keyboardDweebs.net). 36 keys, one mcu (pi pico, way better than the pro micro and has more memory, cheaper too and is available on Amazon). STL files for case is available. Pre made vial firmware available as well. Only downside is that you’ll need to solder some diodes. Other than that it’s pretty cheap to make and put one together. You can go caseless/plateless.

• cantor

  34 557 4.8

  Cantor keyboard, a 42 key diodeless split keyboard.

Cantor by DiePala, Choc, diodeless, cheap “Black pill” mcu, requires two. Caseless/plateless. Pcb is reversible, but you’ll need trrs cable and Jack.

• bgkeeb

  10 82 4.0

https://github.com/sadekbaroudi/bgkeeb should be fairly cheap to produce. I ordered some from JLC and they cost about 4$. Plates came in at 6$ although you could probably just solder the switches without a plate.

There seems to be a Cantor MX version: https://github.com/azhizhinov/cantor/tree/Cherry-MX-version-with-KS-27-support
