Questions
How big is the Binary watch PCB?
It measures 129 × 78.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Binary watch use?
21 parts, built around the ATMEGA328P-AU and DS3231SN#. 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 Binary watch KiCad files?
From the IronHide97/PCB-designs repository on GitHub, at the commit this page was made from: the board is binary_watch/binary watch.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Binary watch design in my own project?
Its repository states no licence, so its author keeps all rights: ask IronHide97 before reusing the design.
