Questions
How big is the Easyppd PCB?
It measures 87 × 72 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Easyppd use?
28 parts, built around the AMS1117-3.3, LMV331TP and SS14. 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 Easyppd KiCad files?
From the KrogeChen/easyprintf repository on GitHub, at the commit this page was made from: the board is hard/easyppd/easyppd.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Easyppd 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).
