Pololu LSM303D 3D Compass and Accelerometer Module

The Pololu LSM303D 3D Compass and Accelerometer Module provides easy access to an advanced 3D magnetometer and accelerometer.

This tiny module features an LSM303D digital sensor with a 3-axis accelerometer and a 3-axis magnetometer. Each of six independent readings is available via I2C and SPI interfaces. The module supports operating voltages from 2.5-5.5V for use with a wide range of microcontrollers.

The LSM303D is ideal for creating a tilt compensated digital compass to keep your robot heading in the right direction.

Libraries are available to simplify use with Arduino and compatible microcontrollers.
