IMU Calibration Block Kit with MPU9250
IMU Calibration Block Kit with MPU9250
The calibration of an inertial measurement unit (IMU) is made simple in this kit by combining an MPU9250 sensor with a 3D-printed cube. The gyroscope contained within the MPU9250 can be calibrated under steady conditions. Similarly, the accelerometer can be calibrated by rotating each axis in the direction of gravity. Lastly, the magnetometer can be calibrated by rotating the block 360 degrees around each axis. The calibration block is specially designed for rotation and calibration of all nine degrees-of-freedom (9-DoF) available to the MPU9250.
