Questions
What parts does the 555-timer use?
7 parts, built around the NE555P. 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 555-timer KiCad files?
From the gearoid-murphy/circuits repository on GitHub, at the commit this page was made from: the board is 555-timer/555-timer.kicad_pcb and its schematic laser-diode-butterfly-mount/laser-diode-butterfly-mount.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 555-timer design in my own project?
Its repository states no licence, so its author keeps all rights: ask gearoid-murphy before reusing the design.
