Questions

How big is the ComsBoard PCB?

It measures 80 × 75 mm and has 2 copper layers, 1.6 mm thick.

What parts does the ComsBoard use?

82 parts. 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 ComsBoard KiCad files?

From the SFBdragon/eee4113f-project repository on GitHub, at the commit this page was made from: the board is PCB Files/ComsBoard.kicad_pcb and its schematic PCB Files/ComsBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the ComsBoard design in my own project?

Its repository states no licence, so its author keeps all rights: ask SFBdragon before reusing the design.
