Summary

STMicroelectronics LSM6DS3 3D accelerometer and 3D gyroscope with SPI interface for advanced motion sensing applications.

Description

The **LSM6DS3 IMU** combines a 3-axis accelerometer and 3-axis gyroscope with programmable full-scale ranges, data rates, and advanced features including tap detection, free-fall detection, orientation sensing, and pedometer functionality. It communicates via SPI interface with configurable filtering and performance modes.
