Questions
How big is the Nodu PCB?
It measures 285 × 94.6 mm and has 2 copper layers, 1.2 mm thick.
What parts does the Nodu use?
130 parts, built around the ATMEGA32U4-AU and BAV70. 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 Nodu KiCad files?
From the swiftrax/Nodu repository on GitHub, at the commit this page was made from: the board is Nodu/Nodu.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nodu design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
