Questions
How big is the USBPD PCB?
It measures 21.5 × 19 mm and has 2 copper layers, 1.6 mm thick.
What parts does the USBPD use?
23 parts, built around the ATTINY1626-MF, FUSB302MPX and AP7384-33Y. 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 USBPD KiCad files?
From the Mr-Bossman/usbPB-ThinkPad repository on GitHub, at the commit this page was made from: the board is board/USBPD.kicad_pcb and its schematic board/USBPD.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the USBPD design in my own project?
Its repository states no licence, so its author keeps all rights: ask Mr-Bossman before reusing the design.
