Questions
How big is the Arduino PCB?
It measures 68.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Arduino use?
46 parts, built around the ATMEGA328P-PU, CH340C, LM358 and AMS1117-3.3. 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 cristobalcuevas/PCB-Designs repository on GitHub, at the commit this page was made from: the board is Arduino/Arduino.kicad_pcb. 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 cristobalcuevas before reusing the design.
