Overview
The LSM303DLH, produced by STMicroelectronics, is a system-in-package that integrates a 3D digital linear acceleration sensor and a 3D digital magnetic sensor. This module is designed to provide comprehensive motion and orientation data, making it ideal for various applications requiring precise sensing of acceleration and magnetic fields.
The device features an I²C serial bus interface that supports standard and fast mode at 100 kHz and 400 kHz, allowing for efficient communication with microcontrollers. It also includes programmable interrupt generators for inertial wake-up/free-fall events and position detection, with thresholds and timing configurable by the user.
The LSM303DLH operates over an extended temperature range from -40 °C to +85 °C and is available in a plastic land grid array package (LGA).
