The 9DOF Razor IMU incorporates three sensors: an ITG-3200 (triple-axis gyro), ADXL345 (triple-axis accelerometer), and HMC5883L (triple-axis magnetometer). Together they give you nine degrees of inertial measurement. The outputs of all sensors are processed by an on-board ATmega328 and output over a serial interface. This enables the 9DOF Razor to be used as a very powerful control mechanism for UAVs, autonomous vehicles and image stabilization systems.
The board comes programmed with the 8MHz Arduino bootloader and some example firmware that demos the outputs of all the sensors. Simply connect to the serial TX and RX pins with an FT232RL USB-to-Serial 3.3V Interface or similar, open a terminal program to 57600bps and a menu will guide you through testing the sensors. You can use the Arduino IDE to program your code onto the 9DOF — just select the Arduino Pro or Pro Mini (3.3V, 8MHz) w/ATmega328 as your board.
The 9DOF operates at 3.3VDC; power supplied to the white JST connector will be regulated down to this operating voltage. Lithium Polymer batteries are an excellent power supply choice; there's a barrel-jack adapter available as well. The output header is designed to mate with the FT232RL interface board linked to above, so you can connect the board to a computer's USB port easily. For a wireless solution, it can be connected to the Bluetooth Mate or an XBee Explorer.
