Questions
What parts does the SobPad use?
56 parts, built around the ATMEGA32U4-AU. 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 SobPad KiCad files?
From the UsrBinLuna/sobPad repository on GitHub, at the commit this page was made from: the board is sobPad.kicad_pcb and its schematic sobPad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SobPad design in my own project?
Its repository states no licence, so its author keeps all rights: ask UsrBinLuna before reusing the design.
