Questions
How big is the Debounced clock PCB?
It measures 74.9 × 40.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Debounced clock use?
31 parts, built around the NE555. 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 Debounced clock KiCad files?
From the marekl123/debounced-clock repository on GitHub, at the commit this page was made from: the board is debounced-clock.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Debounced clock design in my own project?
Its repository states no licence, so its author keeps all rights: ask marekl123 before reusing the design.
