Questions
What parts does the STM32F405 Flight Controller use?
71 parts, built around the LMR33640DDDA, AP7361C-33E, BAT54C and USBLC6-2P6. 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 STM32F405 Flight Controller KiCad files?
From the Allen2331/STM32-Flight-Controller repository on GitHub, at the commit this page was made from: the board is PCB/STM32F405_Flight_Controller.kicad_pcb and its schematic Schematic/FC_Connectors.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32F405 Flight Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask Allen2331 before reusing the design.
