README
README.mdShadowfax
FPV Drone designed from scrach. This design isn't fully custom yet but will get there eventually. I started this project to make a cool drone and learn as much as I can about engineering.
Flight Controller
The meat and potatios, the main computer for the drone.
Transceiver
A low frequency radio to communicate with a remote controller.
Camera Controller
Controls the camera and captures videos and pictures with a high frequency radio for faster communication.
Power Board
Powers the whole stack with 3.3v and connects the ESCs to the input voltage.
Frame
I made a custom frame to fit my custom boards and here it is.

Questions
How big is the Flight controller PCB?
It measures 40 × 40 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Flight controller use?
57 parts, built around the BMP384, MMC5983MA, LSM6DSV and MIC5504-3.3YM5. 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 someonelse20/Shadowfax repository on GitHub, at the commit this page was made from: the board is flight-controller/hardware/flight-controller.kicad_pcb and its schematic ESC/hardware/ESC.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 someonelse20 before reusing the design.
