Questions
How big is the Atom PCB?
It measures 276.9 × 100.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Atom use?
100 parts, built around the WS2812B. 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 Atom KiCad files?
From the bbrfkr/keyboards repository on GitHub, at the commit this page was made from: the board is atom/atom.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Atom 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).
