Questions
How big is the FCS PCB PCB?
It measures 169.5 × 66 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FCS PCB use?
18 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 FCS PCB KiCad files?
From the HannesScript/FCS repository on GitHub, at the commit this page was made from: the board is pcb/FCS_PCB.kicad_pcb and its schematic pcb/FCS_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FCS PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask HannesScript before reusing the design.
