Questions
How big is the Badge PCB?
It measures 27.3 × 27.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Badge use?
48 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 Badge KiCad files?
From the nihcoc/PCBCLOCK repository on GitHub, at the commit this page was made from: the board is Hardware/badge.kicad_pcb and its schematic Hardware/badge.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Badge design in my own project?
Its repository states no licence, so its author keeps all rights: ask nihcoc before reusing the design.
