Summary

STMicroelectronics LSM9DS1 9-axis IMU with SPI interface combining accelerometer, gyroscope, and magnetometer for comprehensive motion and orientation sensing.

Description

The **LSM9DS1 IMU** combines a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer in a single package. It provides comprehensive motion and orientation data with configurable sample rates, filtering, and performance modes. The sensor features separate SPI interfaces for accelerometer/gyroscope and compass modules with advanced configuration options.
