GY521 MPU6050 Module (5 pcs) — 3Axis Gyroscope + 3Axis Accelerometer Breakout Small, readytouse IMU (Inertial Measurement Unit) modules based on the MPU6050 sensor. Each GY521 board integrates a 3axis accelerometer and a 3axis gyroscope in one compact breakout, giving you reliable motion and orientation data over a simple I2C connection. Sold as a pack of 5 identical modules for prototyping, education, or multisensor projects. Why you need this module Combine acceleration and angularrate sensing in a single, compact module to simplify hardware and reduce wiring. Read motion data over I2C with common microcontrollers for fast integration into Arduino, Raspberry Pi, ESP32 and other projects. Use a proven, widely supported sensor (MPU6050) with mature libraries and example code to speed up development. Key benefits Readytouse breakout: MPU6050 SMD sensor mounted on a GY521 PCB with standard pin headers for breadboard or shield connections. Saves design time: integrated sensor and easy I2C interface means fewer components and faster prototyping. Pack of 5: costeffective choice for classrooms, multiplenode systems, or replacement spares.

Typical applications Drone and quadcopter stabilization: realtime angular velocity and acceleration data for flight controllers and autopilots. Robotics and balancing platforms: orientation sensing for selfbalancing robots, gimbals, and navigation systems. Motion tracking and gesture detection: controller input, wearable projects, and basic IMUbased position sensing. What's included 5 x GY521 MPU6050 breakout modules Notes for use Observe proper wiring for I2C (SDA to SDA, SCL to SCL) and common ground with your controller. Confirm the power requirements and voltage regulator configuration on your specific GY521 board before applying 5V. Calibration improves accuracy; use available libraries and examples to calibrate accelerometer and gyroscope offsets. Reliable, compact, and widely supported — the GY521 MPU6050 modules give you an easy way to add accurate 6axis motion sensing to prototyping and production experiments.
