Project Description

This is a personal project for an STM32 flight computer that will be flown on a high-power rocket to achieve the Level 1 high power rocketry certification in Canada. <br>

Capabilities

The computer is able to store flight data from its two sensors:

• ICM42670: 6-axis IMU with a gyroscope and accelerometer
• BME280: Pressure, temperature and humidity sensor

Data from the accelerometer and gyroscope is used to activate the pyro charge and release the rocket's parachute (single-deploy configuration).

Flight data is stored in a 4-megabyte flash memory chip and is offloaded from the computer using MicroSD. <br>

During flight, the computer is powered by a 2S LiPo battery through an XT30 connector.

Programming interfaces: SWD and USB Micro-B.
