Questions
How big is the Catduino PCB?
It measures 45.7 × 38.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Catduino use?
15 parts, built around the ATMEGA32U4 and MIC5219-3.3YM5. 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 Catduino KiCad files?
From the TeamMeanMachine/Electronics repository on GitHub, at the commit this page was made from: the board is 2019/Catduino/Catduino.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Catduino design in my own project?
Its repository publishes it under the Unlicense licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
