Questions
How big is the Flight Controller PCB?
It measures 40 × 40 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Flight Controller use?
89 parts, built around the STM32F722RET6, DPS368XTSA1, W25Q128JVPIQ and RC0402FR-0710KL. 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-III/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).
