Questions
How big is the Fcc to header PCB?
It measures 55.3 × 35.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Fcc to header use?
18 parts, built around the MBR0530. 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 Fcc to header KiCad files?
From the Holy-param/Breadboard-psu repository on GitHub, at the commit this page was made from: the board is fcc to header/fcc to header.kicad_pcb and its schematic breadBoard Power supply.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Fcc to header design in my own project?
Its repository states no licence, so its author keeps all rights: ask Holy-param before reusing the design.
