Questions
How big is the Clock PCB?
It measures 56.1 × 19.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Clock use?
39 parts, built around the 74HC595. 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 Clock KiCad files?
From the alphastint/Clock repository on GitHub, at the commit this page was made from: the board is Clock.kicad_pcb and its schematic Clock.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Clock design in my own project?
Its repository states no licence, so its author keeps all rights: ask alphastint before reusing the design.
