SparkFun HMC6343 Breakout
The SparkFun HMC6343 Breakout provides easy access to a fully integrated electronic compass module capable of computing heading direction accurate to within a couple of degrees. It combines 3-axis magneto-resistive sensors and 3-axis MEMS accelerometers with on-board tilt compensation and magnetic distortion calibration.
All you need is a 3.3 V supply and I²C connections to your microcontroller. The HMC6343 computes heading, pitch, and roll at up to 5 Hz (every 200 ms), with all processing handled by its internal microprocessor and firmware algorithms.
