The Integrated IMU Sensor Module (GY-85)  is a compact and versatile solution for advanced 9-axis motion tracking and orientation sensing. It combines three essential sensors—accelerometer, gyroscope, and digital compass—into a single, integrated system. This module delivers precise measurements for motion, orientation, and heading, making it ideal for robotics, drones, and wearable devices.
