It measures 114.6 × 97.3 mm and has 2 copper layers, 1.69 mm thick.

What parts does the Runar use?

46 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 Runar KiCad files?

From the bgics/runar repository on GitHub, at the commit this page was made from: the board is runar.kicad_pcb and its schematic runar.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Runar design in my own project?

Its repository states no licence, so its author keeps all rights: ask bgics before reusing the design.
