ER-MIMU-16(M02A) Cost Effective Attitude Control MEMS IMU
Introduction
ER-MIMU-16(M02A) is a complete inertial measurement unit with a built-in 3-axis gyroscope, a 3-axis accelerometer, a 3-axis magnetometer, and a pressure sensor. Each inertial sensor combines industry-leading MEMS technology with signal conditioning to deliver optimized dynamic performance. Each sensor has its own dynamic compensation formula that provides accurate sensor measurements.
ER-MIMU-16(M02A) provides a simple and efficient way to integrate accurate multi-axis inertial sensing into industrial systems compared to complex and expensive discrete design solutions. All required motion testing and calibration are part of the factory production process, significantly reducing system integration time. The SPI and register structures provide a simple interface for data collection and configuration control. It is available in a module package measuring approximately 47 mm x 44 mm x 14 mm with a standard connector interface.
