Questions

How big is the Rad base PCB?

It measures 43.2 × 43.2 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Rad base use?

167 parts. 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 Rad base KiCad files?

From the u2key/rad-base repository on GitHub, at the commit this page was made from: the board is rad-base-all-pins/rad-base.kicad_pcb and its schematic rad-base-all-pins/rad-base.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Rad base 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).
