GY521 MPU6050 3 Axis Analog Gyroscope Sensors + Accelerometer Module IIC I2C for Quadcopter 35V (1pcs) Key benefits Combines a 3axis gyroscope and 3axis accelerometer on a single MPU6050 sensor, providing compact and reliable motion sensing for stabilization and navigation tasks. IIC/I2C communication simplifies wiring and integration with microcontrollers and flight controllers that support I2C, reducing development time. Wide operating voltage (3–5 V) makes the module compatible with common hobby and embedded systems without extra level shifting. Small, readytouse breakout form factor lets you add inertial measurement functionality to prototypes, drones, robots, and handheld devices quickly. Key attributes Model: GY521 breakout board carrying the MPU6050 sensor Sensors: 3axis gyroscope + 3axis accelerometer (integrated in MPU6050) Interface: IIC / I2C digital interface for data and control Supply voltage: 3–5 V Package: Single module (1 pcs) Why you need it If you are building a quadcopter, robot, selfbalancing platform, or motionaware device, this module provides essential attitude and movement information (angular rate and linear acceleration) in a single, compact component. It solves the need for accurate, multiaxis motion sensing without bulky wiring or multiple separate sensors. How it solves common problems Reduces component count and board space by integrating gyro and accelerometer. Eases integration via the industrystandard I2C interface, allowing the sensor to share a bus with other peripherals. Operates across typical hobby voltages, avoiding the need for additional power conversion when used with 3.3 V or 5 V systems. Typical applications / use cases Quadcopter flight stabilization and attitude sensing to keep aircraft level and responsive. Mobile robotics and selfbalancing platforms for posture control and motion feedback. Motion detection and gesture recognition in DIY electronics, wearable prototypes, or sensor fusion projects. What's included 1 x GY521 MPU6050 3axis gyroscope + accelerometer module (I2C, 3–5 V) Notes for integration Connect power (3–5 V) and ground, and attach SDA and SCL lines to your controller's I2C pins. Ensure your host supports I2C communication and the chosen logic voltage range. This module offers a straightforward, compact way to add reliable inertial sensing to a wide range of projects that require motion and orientation data.
