The neuro36 by Daniel Haarhoff (aka erkannt/mit_verlauf) is a small 36-key split keyboard optimized for travel.

I wanted a keyboard I could travel with. I need 36 keys and like to have larger keys to rest my thumbs on (probably due my journey having been Ergodox -> gergo) – Daniel.

With its low-profile case and switches, and the nice Chicago steno thumb caps, the neuro36 has definitely reached this goal.

Specs

  • 36 keys
  • low profile, Choc-spaced
  • hotswap or soldered (on main 30 keys)
  • reversible PCB
  • Seeed XIAO RP2040 MCU
  • remaining pins broken out on right hand (hope was to add trackball)
  • low-profile printed case
  • press-fit travel protector
  • thumb keys can be soldered in either orientation

The case is printable without supports, however, the travel protector needs them. Make sure you have good bed adhesion as a warped print will give you a wobbly case. Other than that:

I picked a very small diode footprint by accident. I'd suggest going for something larger if you are up for tweaking the KiCAD project – Daniel.
