Inertial Measure Unit Sensor Replace STIM210 Pure IMU 3 Axis Gyro 3 Axis Accelerometer​

The micro gyroscope assembly is composed of a three-axis gyroscope, a temperature sensor, a signal processing board, a structure and necessary software, and is used for measuring the three-axis/two-axis angular rate of a carrier, and outputting three angular rate data subjected to error compensation (including temperature compensation, installation misalignment angle compensation, nonlinear compensation and the like) through an RS-422 serial port according to an agreed communication protocol.
