Questions

How big is the CapBank PCB?

It measures 46.5 × 76.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the CapBank use?

37 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 CapBank KiCad files?

From the MagGenix/AMF-Generator repository on GitHub, at the commit this page was made from: the board is CapBank/CapBank.kicad_pcb and its schematic AMF-Generator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the CapBank design in my own project?

Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
