Questions
What parts does the OTC use?
82 parts, built around the CP2102N-EK, AP2112K-3.3, HV5523K7-G and TXS0104ED. 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 OTC KiCad files?
From the judge2005/OTC repository on GitHub, at the commit this page was made from: the board is OTC.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the OTC design in my own project?
Its repository states no licence, so its author keeps all rights: ask judge2005 before reusing the design.
