Questions

How big is the Encoder controller PCB?

It measures 60 × 60 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Encoder controller use?

10 parts. 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 Encoder controller KiCad files?

From the adeboni/electronics repository on GitHub, at the commit this page was made from: the board is mega_trackball/hardware/encoder_controller/encoder_controller.kicad_pcb and its schematic alien_screamer/alien_screamer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Encoder controller design in my own project?

Its repository states no licence, so its author keeps all rights: ask adeboni before reusing the design.
