Questions
How big is the Blinker PCB?
It measures 28 × 42.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Blinker use?
28 parts, built around the CR2032. 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 Blinker KiCad files?
From the yun297/blinker repository on GitHub, at the commit this page was made from: the board is blinker.kicad_pcb and its schematic blinker.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Blinker design in my own project?
Its repository states no licence, so its author keeps all rights: ask yun297 before reusing the design.
