Questions
How big is the Blinky PCB?
It measures 50 × 50 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Blinky use?
127 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 Blinky KiCad files?
From the rcls/blinky repository on GitHub, at the commit this page was made from: the board is blinky.kicad_pcb and its schematic blinky.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Blinky design in my own project?
Its repository states no licence, so its author keeps all rights: ask rcls before reusing the design.
