Questions
How big is the Arduino PCB?
It measures 95 × 63 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Arduino use?
32 parts, built around the ATMEGA328P-PU, CH340G and AMS1117-5.0. 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 Arduino KiCad files?
From the gustme/Custom-Arduino repository on GitHub, at the commit this page was made from: the board is arduino/arduino.kicad_pcb and its schematic arduino/arduino.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Arduino design in my own project?
Its repository states no licence, so its author keeps all rights: ask gustme before reusing the design.
