Questions
How big is the ClockOmat PCB?
It measures 30.5 × 114.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ClockOmat use?
92 parts, built around the ATMEGA328P-AU, L7805, BC817 and BC807. 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 ClockOmat KiCad files?
From the cybaer/ClockOmat repository on GitHub, at the commit this page was made from: the board is HW/ClockOmat.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ClockOmat design in my own project?
Its repository states no licence, so its author keeps all rights: ask cybaer before reusing the design.
