From the project
Some work I do for CycloneRocketry
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.

Avionics Board 1: common questions
What microcontroller does the Avionics Board 1 use?
The Avionics Board 1 is built around the ATSAMD21G18, from the Microchip SAM family.
How big is the Avionics Board 1?
The Avionics Board 1 measures 50 × 50 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Avionics Board 1?
63 components, from 36 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Avionics Board 1 design files?
From the djmallek/CycloneRocketry repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Avionics Board 1 design in my own project?
