Questions
How big is the 555Timer PCB?
It measures 41.9 × 29 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 555Timer use?
11 parts, built around the LM555CN. 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 555Timer KiCad files?
From the a10001110101/PCBs repository on GitHub, at the commit this page was made from: the board is 555Timer/555Timer.kicad_pcb and its schematic Full555Timer/Full555Timer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 555Timer 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).
