Questions
How big is the Rusb pd second PCB?
It measures 25.5 × 24.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rusb pd second use?
34 parts, built around the FUSB302BMPX, AMS1117-3.3, AO3401 and BC847. 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 Rusb pd second KiCad files?
From the ambraglow/rusb-pd repository on GitHub, at the commit this page was made from: the board is rusb-pd-second/rusb-pd-second.kicad_pcb and its schematic rusb-pd-second/rusb-pd-second.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rusb pd second design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
