GY-85 9-Axis IMU Sensor Module ITG3205 ADXL345 HMC5883L

The GY-85 Nine-Axis IMU Sensor Module is a highly integrated, low-power motion tracking board designed for advanced robotics, navigation, and stabilization systems. This multi-sensor module combines three high-performance micro-electromechanical systems (MEMS) sensors on a single compact PCB: the ITG3205/ITG3200 3-axis digital gyroscope, the ADXL345 3-axis accelerometer, and the HMC5883L 3-axis digital compass (magnetometer). Together, they provide a complete 9 Degrees of Freedom (9-DOF) inertial measurement system, allowing your project to track orientation, acceleration, and magnetic heading simultaneously.

Equipped with an onboard low-dropout (LDO) voltage regulator and level converters, the GY-85 is fully compatible with both 3.3V and 5V logic levels, making it easy to interface with popular microcontrollers like Arduino, ESP32, STM32, and Raspberry Pi. Communication is handled over a single, shared I2C bus, which significantly reduces wiring complexity and saves valuable I/O pins on your controller. This module is the go-to choice for makers and engineers building quadcopters, self-balancing robots, UAVs, and 3D head-tracking devices.

Features:

• 9-DOF Motion Tracking: Combines a 3-axis gyroscope, 3-axis accelerometer, and 3-axis magnetometer on one board.
• High-Precision Sensors: Features the ITG3205 for angular velocity, ADXL345 for linear acceleration, and HMC5883L for magnetic field sensing.
• I2C Interface: Uses a single I2C bus for all three sensors, simplifying communication and wiring.
• Onboard Voltage Regulator: Integrated 3.3V LDO regulator allows safe operation from 3V to 5V power inputs.
• Wide Dynamic Ranges: User-programmable full-scale ranges for precise measurement tuning.
• Compact and Lightweight: Weighs only 4 grams, making it ideal for weight-sensitive drone and RC aircraft projects.
