MSI360 Micro Inertial Measurement Unit

Introduction

  • Miniaturized IMU
  • High performance IMU
  • Low power consumption
  • Full temperature compensation.

MSI360 is a is a miniaturized, 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.
