The Klorball35, created by Dan Bowles (aka longwave), is a 35-key, column-staggered, low-profile split keyboard with an integrated trackball.
This project started after seeing what was possible in Ergogen from the Kivipallur keyboard. I built a KLOR and loved it, then I bought a Keyball39 kit and loved that. The only issue with the Keyball39 was that it was not splayed and I wanted to give Choc switches a try again – Dan Bowles.
This board is diodeless and uses Helios MCUs.
