Questions
How big is the Controller PCB?
It measures 74.7 × 30 mm and has 4 copper layers, 1.66 mm thick.
What parts does the Controller use?
77 parts, built around the AP2205-W5, ESP32-H2-MINI-1U, MCP73833 and THB001P. 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 Controller KiCad files?
From the StuckAtPrototype/Thumbtroller repository on GitHub, at the commit this page was made from: the board is hardware/controller.kicad_pcb and its schematic hardware/controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask StuckAtPrototype before reusing the design.
