LSM303DLM 3D Compass and Accelerometer Carrier with Voltage Regulators
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.

- Datasheet for the ST LSM303DLM 3-axis accelerometer and 3-axis magnetometer.
- 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.
