Questions

How big is the Usb gpio PCB?

It measures 95 × 113 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Usb gpio use?

222 parts, built around the RP2040, LM321, TLV62568DBV and W25Q128JVSIQ. 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 gpio KiCad files?

From the petersn/usb-gpio repository on GitHub, at the commit this page was made from: the board is board/board.kicad_pcb and its schematic board/board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Usb gpio design in my own project?

Its repository states no licence, so its author keeps all rights: ask petersn before reusing the design.
