BNO055

The BNO055 by Bosch Sensortec is a 9-axis IMU that we use to determine the rocket's acceleration. It has an accelerometer, gyroscope, and magnetometer that it automatically fuses together to give us acceleration in a global frame of reference. 9-axis refers to the 3 axes (X, Y, Z) of the accelerometer, 3 axes of the gyroscope, and 3 axes of the magnetometer. The BNO055 is connected to the Teensy over I2C.

The datasheet for the BNO055 is available here. (Updated 2021)

We use the Adafruit_BNO055 library to interface with the BNO055.
