Questions
How big is the Soc PCB?
It measures 91.4 × 73.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Soc use?
64 parts, built around the MAX3232ID, DS3234S# and TX 1. 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 Soc KiCad files?
From the mattstock/bexkat1 repository on GitHub, at the commit this page was made from: the board is kicad/soc.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Soc design in my own project?
Its repository states no licence, so its author keeps all rights: ask mattstock before reusing the design.
