MSI3000E Micro Inertial Measurement Unit


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

The MSI3000E is a micro inertial measurement unit which can output angular velocity and acceleration information in three axial directions. With internal shock absorption structure, it has good resistance to vibration and shock. It can meet the performance requirements of gyroscopes and accelerometers under different temperature conditions after modeling and calibration.
