9 Axis Atmega328 Sensor Module IMU AHRS ITG3200/ITG3205 Gyro ADXL345 Accelerometer HMC5883L Magnetometer 3-5V DC Geekcre

Overview The 9DOF IMU uses three sensors ITG3200 3205 MEMS three axis gyroscope ADXL345 three axis accelerometer and HMC5883L three axis magnetometer to provide you with nine axis inertial measurements The output of all sensors is processed by an on board ATMEGA328 and output via a serial interface This makes the 9DOF IMU a very powerful control mechanism for unmanned aircraft unmanned vehicles and image stabilization systems Specifications Using the chip Atmega328 ITG3200 ITG3205 ADXL345 HMC5883LPower supply 3 5V DCOutput port serial port can be connected to Bluetooth XBee communication module etc provide forenvironment algorithm reference source codeSize 49 53 x 27 94 mm Test Data Standard calibration It might be good to power up the Razor a few minutes before calibration so the sensors can warm up Calibrating the sensors the first time can be a little tricky but lets go Open for Razor AHRS Razor AHRS ino using forand find the section USER SETUP AREA SENSOR CALIBRATION This is where you put the calibration values later Connect the Razor AHRS to your computer set the correct serial port in forand open the Serial Monitor If you didnt change the firmware defaults you should see lots of output like this YPR 155 73 76 48 129 51Set the firmware output mode to calibration by sending the string oc You should now see output like this accel x y z min max 5 00 1 00 25 00 29 00 225 00 232 00Calibrating the accelerometer Well try to find
