Modern MEMS (microelectromechanical systems) are amazing. This chip, the MPU9250 from Invensense, is a 3 axis accelerometer, 3 axis gyro, and 3 axis compass, all in one tiny package. It has an onboard processor for sensor fusion and looks perfect for a quadcopter, home spacecraft, or body sensing. The interface to JeeNodes makes wireless sensing with this board a snap.
The MPU9250 is 3.3V only, so be careful connecting it to a 5V board.
