Questions
How big is the ReGary PCB?
It measures 38 × 38 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ReGary use?
39 parts, built around the SN74CBT16210DL, LM1117-3.3 and TPS73643DBV. 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 ReGary KiCad files?
From the jbilander/ReGary repository on GitHub, at the commit this page was made from: the board is KiCad/ReGary.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ReGary design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
