==Introducion==
[[File:9DOF stick.jpg|300px]]

The 9DOF Sensor board is a very small sensor board with 9 degrees of freedom. It includes the ADXL345 accelerometer, the HMC5883L magnetometer, and the ITG-3205 gyro. The board has a simple I2C interface and a mounting hole for attaching it to your project. Also, The small volume of the snesor board allows it to be easily mounted in just about any application. If you need a simple and tiny board that gives you 9 degrees of freedom, this would be a good choice.

==Features==
*Tiny!
*Two mounting holes
*ADXL345 accelerometer
*ITG-3200 gyro
*HMC5883L magnetometer
*3.3V input
*I2C interface

You can get the data of [http://www.geeetech.com/wiki/index.php/HMC5883L_Triple_Axis_Magnetometer_Breakout ADXL345], [http://www.geeetech.com/wiki/index.php/ITG3205_Triple_Axis_Gyroscope_Breakout ITG3205] and [http://www.geeetech.com/wiki/index.php/HMC5883L_Triple_Axis_Magnetometer_Breakout HMC5883L] seperately using the relating example code or using Razor AHRS(Attitude and Heading Reference System) Firmware to compute precisely orientation of the board in space by reading the data from the 3 sensors.

==AHRS Example code==
Using your Arduino open the file Razor_AHRS/Razor_AHRS.pde from your download [https://dev.qu.tu-berlin.de/projects/sf-razor-9dof-ahrs/files Razor AHRS Firmware package]. Don't drag the file into your IDE directly.
