Overview
The LSM303DLHC, also available in the LSM303DLHCTR variant, is a system-in-package developed by STMicroelectronics. It integrates a 3D digital linear acceleration sensor and a 3D digital magnetic sensor, making it an ultra-compact high-performance eCompass module. This device is ideal for applications requiring precise orientation and motion detection, such as tilt-compensated compasses, map rotation, and position detection.
