Questions
How big is the Relay timer555 PCB?
It measures 80 × 48 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Relay timer555 use?
40 parts, built around the IR204-A-L. 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 Relay timer555 KiCad files?
From the eavcodes/relay-timer555 repository on GitHub, at the commit this page was made from: the board is sch/relay-timer555/relay-timer555.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Relay timer555 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
