Questions

What parts does the Eggtimer pcb use?

112 parts, built around the BD70522GUL-E2, TLMS1000-GS08, 2N7002P,215(ES) and RSX301L-30TE25. 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 Eggtimer pcb KiCad files?

From the antonloof/eggtimer repository on GitHub, at the commit this page was made from: the board is eggtimer_pcb/eggtimer_pcb.kicad_pcb and its schematic eggtimer_pcb/eggtimer_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Eggtimer pcb design in my own project?

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