Questions
How big is the Arduino charger PCB?
It measures 79.6 × 51.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Arduino charger use?
51 parts, built around the ATMEGA328P-AU, CH340C, AMS1117-3.3 and SY7628. 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 charger KiCad files?
From the Andy-Cheng1017/Arduino-charger repository on GitHub, at the commit this page was made from: the board is Arduino charger.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Arduino charger design in my own project?
Its repository states no licence, so its author keeps all rights: ask Andy-Cheng1017 before reusing the design.
