IMU

5 parts

6-axis (accel + gyro) inertial units for attitude estimation, robotics and stabilization. Fused with a filter (Madgwick/Kalman), they provide orientation at hundreds of hertz.

How to choose

BMI/LSM/ICM series all work; pick by gyro noise and power budget.
If you need heading, add a magnetometer or choose a 9-axis part — gyros alone drift in yaw.
