Questions
How big is the Polifemo PCB?
It measures 53.3 × 105.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Polifemo use?
53 parts, built around the ATMEGA328P-AU and LM3914. 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 Polifemo KiCad files?
From the polifactory-polimi/Polifemo repository on GitHub, at the commit this page was made from: the board is schematic/polifemo.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Polifemo design in my own project?
Its repository states no licence, so its author keeps all rights: ask polifactory-polimi before reusing the design.
