Introduction: THE 9DOF IMU ITG3200 / ADXL345 / HMC5883L 9DOF RAZOR IMU AHRH UART SPI I2C COMMUNICATION
This is the 9DOF (Degrees Of Freedom) IMU (Inertial Measurement
Unit) module that has 3 integrated sensor in one module board the ITG-3200 (Triple Axis Digital Output Gyroscope), ADXL345 (13bit Resolution ±16g Triple Axis Accelerometer), HMC5883L (Triple Axis, Digital Magnetometer) that provide you’re a 9 degrees of inertial measurement. The output of the sensors are process by the microcontroller. This enable the 9DOF module to be used as control mechanism like UAV (Autonomous Vehicles), Image stabilization system, or control mechanism. Some of board designs comes with programmed with 8MHz bootloader (STK500V1) that demonstration of the output of all the sensor just simply connect to the serial TX and RX pins with your USB TTL then open your Serial Terminal that runs at 57600bps.
