Protieusz shared the Gerber files and case of his unibody split 78-BRUCE, which is a condensed version of the Batarang and Armored Batarang models.
So I recently designed a condensed version of the Batarang which I called the 78-BRUCE. It has a interchangeable 34mm or 25mm trackball, 34keys column staggered with integrated RP2040 with hot swap – Protieusz.
Specs
- 34 keys
- MX, hotswap
- on-board RP2040 MCU
- trackball (25 or 34 mm, PMW3360 sensor)
- QMK
- 3D-printed case
