Questions

How big is the 24h timer switch PCB?

It measures 40.7 × 26.9 mm and has 2 copper layers, 1.6 mm thick.

What parts does the 24h timer switch use?

14 parts, built around the ATTINY85-20PU, AMS1117-5.0 and AO4620. 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 24h timer switch KiCad files?

From the ikatkov/24h-timer-switch repository on GitHub, at the commit this page was made from: the board is kicad/24h-timer-switch.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the 24h timer switch design in my own project?

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