A very important component of the sideboard is the IMU [MPU-6050](https://www.invensense.com/products/motion-tracking/6-axis/mpu-6050/) from Invensense. The [MPU-6050](https://www.invensense.com/products/motion-tracking/6-axis/mpu-6050/) determines the board orientation by combining a 3-axis gyroscope and a 3-axis accelerometer on the same silicon die, together with an onboard Digital Motion Processor™ (DMP™), which processes complex 6-axis MotionFusion algorithms. The DMP™ offers many features, such as:
