Klorball35 is a 35-key, column-staggered, low-profile split keyboard with an integrated optical trackball. It's derived from KLOR and Keyball, built with Kivipallur as a starting point in Ergogen, and designed around Kailh Choc V1 switches, an 0xCB Helios (RP2040) controller per half, and a PixArt PMW3360 sensor on the right hand.
Each half carries a 5-column × 3-row main matrix plus a 3-key (left) and 2-key (right)thumb cluster. The right hand gives up one key to make room for the trackball, so the two halves are 18 (left) + 17 (right) = 35 keys.
