Questions
What parts does the Usb use?
12 parts, built around the ATTINY45-20PU. 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 Usb KiCad files?
From the Pornesh/PCB-Design repository on GitHub, at the commit this page was made from: the board is usb/usb.kicad_pcb and its schematic csp/Buck converter/Buck converter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usb design in my own project?
Its repository states no licence, so its author keeps all rights: ask Pornesh before reusing the design.
