SwagRocket555: Active speed brake controller for model rocket target altitude competition

SwagRocket555 was designed to ace model rocket target altitude competitions. The goal was to deploy a speed brake based on the rocket dynamics to make a rocket stop at a specific altitude. The control board is a Teensy 3.6 shield, with a 3 axis gyro, a 3 axis low-g accelerometer, a 1 axis high-g accelerometer, a barometer, and a differential pressure sensor (for pitot tube). It actuates a servo (for extending the speed brake) and ignites a electric match (for deploying a chute).
