Questions
How big is the Arduinopcb PCB?
It measures 58.4 × 68.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Arduinopcb use?
26 parts, built around the ATMEGA328P-AU, 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 Arduinopcb KiCad files?
From the rakshitsh45/Custom-Arduino-Uno repository on GitHub, at the commit this page was made from: the board is arduinopcb.kicad_pcb and its schematic arduinopcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Arduinopcb 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).
