The LSM303DLMTR is a triple axis MEMS accelerometer combined with a triple axis magnetic sensor.
This arrangement allows for the LSM303 to perform 6D orientation detection.
You can communicate with the sensor using a simple I2C interface.
Analog supply voltage should be between 2.16 to 3.6VDC.

• +-1.3 to +- 8.1 Gauss magnetic field full-scale
• Digital supply voltage IOs: 1.8 V
• 16-bit data out
• I2C interface
• Embedded self-test
