Questions
How big is the Koeklok Main PCB?
It measures 20 × 50.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Koeklok Main use?
25 parts, built around the ATTINY3216-SF, FT230XS-R and DS3231MZ+. 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 Koeklok Main KiCad files?
From the koenk/koeklok repository on GitHub, at the commit this page was made from: the board is pcb/Module-Main/Koeklok-Main.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Koeklok Main design in my own project?
Its repository states no licence, so its author keeps all rights: ask koenk before reusing the design.
