Questions
How big is the Epd Project PCB?
It measures 38.3 × 28.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Epd Project use?
20 parts. 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 Epd Project KiCad files?
From the Techiehari/Epd_Project repository on GitHub, at the commit this page was made from: the board is Epd_Project.kicad_pcb and its schematic Epd_Project.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Epd Project design in my own project?
Its repository states no licence, so its author keeps all rights: ask Techiehari before reusing the design.
