Questions
How big is the USB PCB?
It measures 70 × 60 mm and has 4 copper layers, 1.52 mm thick.
What parts does the USB use?
25 parts, built around the TUSB321RWBR, ESDA25L, TS3USB221ARSE and TPD1E05U06DPYR. 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 SPIRIT-org/USB-test repository on GitHub, at the commit this page was made from: the board is USB-rev-1/USB.kicad_pcb and its schematic USB-rev-1/USB.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 SPIRIT-org before reusing the design.
