Questions
How big is the Arduino PCB?
It measures 74.5 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Arduino use?
19 parts, built around the ATMEGA328-PU and DHT11. 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 Serialize71/Arduino-PCB repository on GitHub, at the commit this page was made from: the board is arduino.kicad_pcb and its schematic 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 publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
