Questions
How big is the Trackball PCB?
It measures 27.5 × 33.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Trackball use?
36 parts, built around the MKL03Z32VFK4, CMI126603D08 and MIC5504-3.3YM5. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Trackball KiCad files?
From the UltimateHackingKeyboard/trackball-electronics repository on GitHub, at the commit this page was made from: the board is trackball.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Trackball design in my own project?
Its repository states no licence, so its author keeps all rights: ask UltimateHackingKeyboard before reusing the design.
