LSM303D 3D Compass and Accelerometer Carrier with Voltage Regulator
The LSM303D 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 ±16 g and ±2 to ±12 gauss, are available through I²C and SPI interfaces. This LSM303 carrier board includes a 3.3 V voltage regulator and integrated level shifters that allows operation from 2.5 to 5.5 V, and the 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards.
