Questions
How big is the Usb pd PCB?
It measures 45 × 20 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Usb pd use?
15 parts, built around the AMS1117-3.3, CYPD3177-24LQXQ and AO3401A. 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 pd KiCad files?
From the scooterthedev/usb-pd repository on GitHub, at the commit this page was made from: the board is usb-pd.kicad_pcb and its schematic usb-pd.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usb pd design in my own project?
Its repository states no licence, so its author keeps all rights: ask scooterthedev before reusing the design.
