The LSM303DLM combines a digital 3-axis accelerometer and 3-axis magnetometer into a single package that is ideal for making a tilt-compensated compass. The six independent readings, whose sensitivities can be set in the ranges of ±2 to ±8 g and ±1.3 to ±8.1 gauss, are available through an I²C interface. The carrier board operates from 2.6 to 5.5 V and has a 0.1″ pin spacing.

Clearance: This board is being replaced by the newer LSM303DLHC carrier (which is pin-compatible) and LSM303D carrier.

Using LSM303DLH for a tilt-compensated electronic compass (1MB pdf)
An application note by ST on how to use the LSM303DLH as a tilt-compensated compass. This application note mostly applies to the very similar LSM303DLM as well (when replacing the DLH with the DLM, the main difference to note is that the magnetometer Y and Z registers have been swapped).
LSM303DLM Orangutan example project (5k zip)
This sample program shows how to use an LSM303DLM 3D compass and accelerometer carrier with an Orangutan robot controller to build a tilt-compensated digital compass. The AVR Studio project is set up for an ATmega328P microcontroller, but it will work on other Orangutans with simple changes to the project configuration.
