Questions
How big is the Proto PCB?
It measures 47.3 × 53.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Proto use?
55 parts, built around the AP131-30WG. 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 Proto KiCad files?
From the ioces/haptick repository on GitHub, at the commit this page was made from: the board is hardware/electronics/proto/proto.kicad_pcb and its schematic hardware/electronics/interface/interface.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Proto design in my own project?
Its repository states no licence, so its author keeps all rights: ask ioces before reusing the design.
