IMU381ZA

 

The ACEINNA IMU381ZA is an improved, pin-compatible version of the popular IMU380ZA. It's a miniature fully calibrated 6 DOF inertial measurement system designed for demanding embedded applications that require a complete dynamic measurement solution in a robust low-profile package. IMU381ZA provides a standard SPI bus for cost-effective board-to-board communications.

The IMU381ZA-200 has a +/-200dps gyro FSR, and +/-4g accelerometer FSR. The IMU381ZA-400 has a +/-400dps gyro FSR, and +/-8g accelerometer FSR.
