This is a 9DOF ArduIMU includes three sensors - an ITG-3205 (triple-axis gyro), ADXL345 (triple-axis accelerometer), and HMC5883L (triple-axis magnetometer). This board comes programmed with the 5V/16MHz Arduino Pro mini328 bootloader, simply connect to the serial TX and RX pins with a 5V FTDI Basic Breakout.
The outputs of all sensors are processed by an on-board ATmega328 and output over a serial interface.This enables the 9DOF ArduIMU to be used as a very powerful control mechanism for UAVs, autonomous vehicles and image stabilization systems.
ITG-3205 - triple-axis digital-output gyroscope
ADXL345 - 13-bit resolution, ±16g, triple-axis accelerometer
HMC5883L - triple-axis, digital magnetometer
Outputs of all sensors processed by on-board ATmega328 and sent out via a serial stream
Output pins match up with FTDI Basic Breakout, Bluetooth Mate, XBee Explorer
ON-OFF control switch and reset switch

I made a headtracker out of this board. It has an inbuilt Atmega328 which you can use for processing the IMU data and for creating a PPM signal which you can feed into your transmitter. Overall quality seems to be ok. Worked right away. Only strange thing is, that the FTDI description on the board says 3.3V but in the text above it says connect 5V. Works with 5V though, but would not recommend as it looks like the IMU sensors are directly attached to 3.3V line. Great product and if you want to use it as a headtracker without drift then this is your choice.
