Questions
How big is the Beerduino PCB?
It measures 68 × 53 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Beerduino use?
53 parts, built around the ATMEGA168P-20AU, FT2232D, LE33CZ-TR and BC56-12GWA. 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 Beerduino KiCad files?
From the Maltheren/Beerduino repository on GitHub, at the commit this page was made from: the board is rev_1/Beerduino.kicad_pcb and its schematic rev_1/Beerduino.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Beerduino design in my own project?
Its repository states no licence, so its author keeps all rights: ask Maltheren before reusing the design.
