Questions
How big is the Flight controller PCB?
It measures 35 × 43 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Flight controller use?
25 parts, built around the ESP32-C3-WROOM-02-H4, AMS1117-3.3 and ICM-20602. 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 Flight controller KiCad files?
From the fredch16/flight-controller repository on GitHub, at the commit this page was made from: the board is flight-controller.kicad_pcb and its schematic flight-controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Flight controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask fredch16 before reusing the design.
