    The ER-MIMU-M01A High Performance MEMS IMU is a miniaturized, high-precision inertial component that contains three-axis gyroscope and three-axis accelerometer information. Temperature compensation is performed through the bias stability and scale of each axis to improve its measurement accuracy.
