Questions

How big is the Project Aurora PCB?

It measures 285 × 94.6 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Project Aurora use?

275 parts, built around the MK20DX256VLH7. 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 Project Aurora KiCad files?

From the Project-Aurora/Project-Aurora repository on GitHub, at the commit this page was made from: the board is Project-Aurora.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Project Aurora design in my own project?

Its repository publishes it under the GPL-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).
