A breakout board combining a 3-axis accelerometer and 3-axis magnetometer in a single module, based on the LSM303DLHC sensor. Use the accelerometer to detect orientation (which way is down) and the magnetometer to find magnetic north — together they provide full compass heading and tilt-compensated orientation data.

The board communicates over I2C and includes level-shifting circuitry for safe operation with both 3.3V and 5V microcontrollers. An Arduino library is available for quick setup.
