Questions
How big is the USB PiDU PCB?
It measures 71.5 × 56 mm and has 2 copper layers, 1.6 mm thick.
What parts does the USB PiDU use?
49 parts, built around the ATMEGA328P-AU, FT232RL and AP2280-2WG. 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 PiDU KiCad files?
From the PhirePhly/USB-PiDU repository on GitHub, at the commit this page was made from: the board is USBPiDU_pcb/USBPiDU.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the USB PiDU design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
