Questions
How big is the Flight Controller PCB?
It measures 50 × 50 mm and has 4 copper layers, 1.58 mm thick.
What parts does the Flight Controller use?
89 parts, built around the NRF24L01, MIC5528-3.3YMT-TR, ICM-42670-P and USBLC6-2SC6. 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 Flynsky/Aeolus repository on GitHub, at the commit this page was made from: the board is STM32_FC/Hardware/Flight_Controller/Flight_Controller.kicad_pcb and its schematic Groundstation/Hardware/GS_controller/Comkicad_sch.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 Flynsky before reusing the design.
