Questions
How big is the BinaryClock PCB?
It measures 28.4 × 41.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BinaryClock use?
20 parts, built around the ATMEGA328-AU, DS3231S# and MC33269D. 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 BinaryClock KiCad files?
From the JaredWright/BinaryClock repository on GitHub, at the commit this page was made from: the board is pcb/BinaryClock.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BinaryClock design in my own project?
Its repository states no licence, so its author keeps all rights: ask JaredWright before reusing the design.
