Creators! Feel free to tip me off about your keyboard related projects to bring them to 100K readers.

Squashkb's offset ortholinear Lesovoz has inspired many keyboard models, the Ballz-Out by Protieusz is the latest in the long line of successors. What makes the Ballz-Out unique is the trackball/trackpad support on the same model:

I designed an open source Lesovoz-like keeb but with two options of pointing device on it (25/34mm trackball or Azoteq 43mm), named Ballz Out. The PCB has two connections for the two types of pointing device ready – Protieusz.

The board fits Rain's Hubris case, and is also compatible with a number of other cases like the Campsite, Pomelo, Carpool, Barca, Coriander, etc.


  • 28-30 keys, offset ortholinear
  • MX, soldered
  • on-board RP2040 MCU
  • trackball (PMW3360) and trackpad (Azoteq 43mm) support
  • roller encoder (optional)
