Questions
How big is the FCHardware PCB?
It measures 39 × 39 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FCHardware use?
52 parts, built around the AP2112K-3.3, ICM-42688-P, USBLC6-2SC6 and SMBJ28A. 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 FCHardware KiCad files?
From the DiScarlet/FlightController repository on GitHub, at the commit this page was made from: the board is FCHardware/FCHardware.kicad_pcb and its schematic FCHardware/Converter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FCHardware design in my own project?
Its repository states no licence, so its author keeps all rights: ask DiScarlet before reusing the design.
