Questions
How big is the Miniarduino PCB?
It measures 32.2 × 20 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Miniarduino use?
21 parts, built around the ATMEGA328-AU, FT232RL and UX60-MB-5ST. 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 Miniarduino KiCad files?
From the siredmar/keychainavr repository on GitHub, at the commit this page was made from: the board is miniarduino.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Miniarduino design in my own project?
Its repository states no licence, so its author keeps all rights: ask siredmar before reusing the design.
