Questions

How big is the 555 timer example PCB?

It measures 79.9 × 115.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the 555 timer example use?

6 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 example KiCad files?

From the adrianwojcikpp/Microprocessor-system-examples-2022-23 repository on GitHub, at the commit this page was made from: the board is FT/kicad/555 Timer Example/555_timer_example.kicad_pcb and its schematic FT/kicad/555 Timer Example/555_timer_example.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the 555 timer example design in my own project?

Its repository states no licence, so its author keeps all rights: ask adrianwojcikpp before reusing the design.
