MSI310D Micro Inertial Measurement Unit


  • Miniaturized IMU
  • Cost-effective
  • Low power consumption
  • Full temperature compensation.

MSI310D is a generalized, high-precision IMU, which contains three-axis gyroscope and three-axis accelerometer. It applies temperature compensation to the bias and scale of each axis to improve its measurement accuracy.
