Questions

What parts does the Device plan use?

29 parts, built around the ATTINY2313A-SU. 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 Device plan KiCad files?

From the lyase/hello-bulb repository on GitHub, at the commit this page was made from: the board is board/device_plan.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Device plan design in my own project?

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