README
README.mdCyclone Rocketry
This is an avionics control board for Iowa State's Cyclone Rocketry club. Our rocketry must carry a payload to a target altitude of 10,000ft. Score is determined by how close a team's rocket can get to the target altitude, among other things. To ensure we hit our target altitude, we have an air brakes system which actively calculates when and how long it needs to deploy it's air brakes system. The board additionally provides data-logging and radio-relayed GPS tracking.

Questions
What parts does the CircularM0 - AvionicsProcessor use?
63 parts, built around the ATSAMD21G18A-AU, MPL3115A2R1, ECS-.327-12.5-17X-TR and BNO055. 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 CircularM0 - AvionicsProcessor KiCad files?
From the djmallek/CycloneRocketry repository on GitHub, at the commit this page was made from: the board is Board5 - Circular Feather/Circular Avionics/CircularM0 - AvionicsProcessor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CircularM0 - AvionicsProcessor design in my own project?
Its repository states no licence, so its author keeps all rights: ask djmallek before reusing the design.
