​Product Description​

The Inertial Measurement Unit (IMU) is a compact, high-shock-resistant device designed for precise navigation, control, and dynamic measurement of moving carriers. It integrates a ​triaxial MEMS gyroscope​ and ​triaxial accelerometer​ with advanced error compensation algorithms (including temperature, installation misalignment, and nonlinear corrections). Processed data is output via a customizable SPI interface, while built-in sensors (magnetometer, barometer) enable comprehensive environmental sensing
