Questions
How big is the Atom47 PCB?
It measures 242.2 × 72.1 mm and has 2 copper layers, 1.2 mm thick.
What parts does the Atom47 use?
142 parts, built around the ATMEGA32U2-AU and USBLC6-2SC6. 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 Atom47 KiCad files?
From the evyd13/atom47 repository on GitHub, at the commit this page was made from: the board is pcb-files/rev4/atom47.kicad_pcb and its schematic pcb-files/rev4/atom47.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Atom47 design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
