About this manual

The LSM303DLM is a system-in-package sensor module combining a 3D digital linear acceleration sensor and a 3D digital magnetic sensor. It features selectable full-scale ranges for both acceleration (±2g/±4g/±8g) and magnetic field (±1.3 to ±8.1 gauss). The device includes an I2C serial interface supporting standard (100 kHz) and fast (400 kHz) modes.
