9DOF Inertial Measurement Board

The 9DOF Razor IMU incorporates four sensors—a LY530AL (single-axis gyro), LPR530AL (dual-axis gyro), ADXL345 (triple-axis accelerometer), and HMC5843 (triple-axis magnetometer)—to provide nine degrees of inertial measurement. The outputs of all sensors are processed by an onboard ATmega328 and transmitted over a serial interface. Building on the work of Jordi Munoz and many others, the 9DOF Razor can function as an Attitude and Heading Reference System (AHRS), making it a powerful control platform for UAVs, autonomous vehicles, and image stabilization systems.
