Questions
How big is the Flight Controller PCB?
It measures 41 × 41 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Flight Controller use?
103 parts, built around the AT7456E, STM32F722RET6, DPS310 and W25Q128JVEIQ. 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 benwys/SparrowHawk repository on GitHub, at the commit this page was made from: the board is hardware/Sparrow-II/Flight Controller.kicad_pcb and its schematic hardware/Sparrow-I/Flight Controller - carrier board.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 publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
