Questions
How big is the Io modul PCB?
It measures 50 × 25 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Io modul use?
25 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 Io modul KiCad files?
From the ravit123/iousb repository on GitHub, at the commit this page was made from: the board is pcb/io_modul.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Io modul design in my own project?
Its repository states no licence, so its author keeps all rights: ask ravit123 before reusing the design.
