Questions
How big is the Arduino nano PCB?
It measures 21 × 44.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Arduino nano use?
26 parts, built around the ATMEGA328P-AU, CH340G and MBR0520L-TP. 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 nano KiCad files?
From the mryashrk/Arduino-nano-pcb-design repository on GitHub, at the commit this page was made from: the board is Arduino nano.kicad_pcb and its schematic Arduino nano.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Arduino nano design in my own project?
Its repository states no licence, so its author keeps all rights: ask mryashrk before reusing the design.
