Adis16488 Replacement Sensors Mems Inertial Measurement Unit
Sensor Imu Accelerometer Gyro The 16488HA inertial measurement unit is a complete inertial system
with a built-in three-axis gyroscope and a three-axis
accelerometer, which is used to measure the three-axis angular
rate, acceleration and other parameters of the carrier, and output
the data after error compensation (including temperature
compensation, installation misalignment angle compensation,
nonlinear compensation, etc.) through SPI according to the
communication protocol.
