The 9DOF IMU module incorporates three sensors – an ITG-3200 (MEMS triple-axis gyro), ADXL345 (triple-axis accelerometer), and HMC5883L (triple-axis magnetometer) – to 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 module 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 (stk500v1) and some example firmware that demos the outputs of all the sensors. Simply connect to the serial TX and RX pins with a 3.3V FTDI Basic Breakout, 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.
