Questions
How big is the ClockBoard PCB?
It measures 34.3 × 28.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ClockBoard use?
12 parts, built around the PN2222A. 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 ClockBoard KiCad files?
From the FoxyHawk/cableTester repository on GitHub, at the commit this page was made from: the board is ClockBoard/ClockBoard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ClockBoard design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
