Questions
How big is the Digital Clock PCB?
It measures 128 × 86 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Digital Clock use?
121 parts. 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 Digital Clock KiCad files?
From the Fliperdos/Digital-Clock repository on GitHub, at the commit this page was made from: the board is digital_clock/digital_clock.kicad_pcb and its schematic digital_clock/digital_clock.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Digital Clock design in my own project?
Its repository states no licence, so its author keeps all rights: ask Fliperdos before reusing the design.
