Questions
How big is the Drone flight controller PCB?
It measures 102 × 49 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Drone flight controller use?
148 parts, built around the ATMEGA328P-AU, STM32F103R8T6, 74AHC1G125GW and 74HC245D. 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 Drone flight controller KiCad files?
From the A1DS19/drone-flight-controller repository on GitHub, at the commit this page was made from: the board is pcb/drone-flight-controller.kicad_pcb and its schematic pcb/ATMEGA238P-plus-components.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Drone flight controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask A1DS19 before reusing the design.
