Questions
What parts does the Clock1.2 use?
40 parts, built around the ATTINY1616-MN and RV-3028-C7. 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 Clock1.2 KiCad files?
From the KIPudding/Binary_watch repository on GitHub, at the commit this page was made from: the board is Clock1.2/Clock1.2.kicad_pcb and its schematic Clock/Clock/Clock.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Clock1.2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask KIPudding before reusing the design.
