Need a tight and tidy way to measure 6-degrees of freedom? The SparkFun IMU Digital Combo Board, measures pitch, roll, yaw, and rate of acceleration on each axis in a very flat package!
This is a simple breakout for the ADXL345 accelerometer and the ITG-3200 gyro. With this board, you get a full 6 degrees of freedom. The sensors communicate over I2C and one INT output pin from each sensor is broken out. If you need a simple and tiny board that gives you 6 degrees of freedom, this would be a good choice.
