Questions
How big is the Monostable PCB?
It measures 40 × 29.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Monostable use?
10 parts, built around the NE555 and B3F-1000. 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 Monostable KiCad files?
From the hellraiserinchief/555_timer repository on GitHub, at the commit this page was made from: the board is monostable.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Monostable design in my own project?
Its repository states no licence, so its author keeps all rights: ask hellraiserinchief before reusing the design.
