Questions
How big is the 555 timer PCB?
It measures 45.8 × 43.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 555 timer use?
13 parts, built around the BC548. 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 smartinternz02/SPS-9275-Water-Level-Controller-using-555-Timer repository on GitHub, at the commit this page was made from: the board is 555 timer.kicad_pcb. 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 smartinternz02 before reusing the design.
