The 9DOF Sensor stick is a very small sensor board with 9 degrees of freedom. It includes the ADXL345 accelerometer, the HMC5883 magnetometer, and the ITG-3200 gyro. The 'stick' has a simple I2C interface and a mounting hole for attaching it to your project. Also, the board is a mere 0.036" thick (0.093" overall), allowing it to be easily mounted in just about any application.
