Questions
How big is the Io pad PCB?
It measures 70 × 105 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Io pad use?
33 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 pad KiCad files?
From the pelmin404/io_pad repository on GitHub, at the commit this page was made from: the board is kicad/IO_Pad.kicad_pcb and its schematic kicad/IO_Pad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Io pad design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
