Questions

What parts does the Blinker use?

14 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 Blinker KiCad files?

From the Lunar-Academy/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 Lunar-Academy before reusing the design.
