GY521 MPU6050 Module 3 Axis gyro sensors+Accelerometer Model 1 A compact, readytouse 6axis motion sensor module that combines a 3axis gyroscope and a 3axis accelerometer (MPU6050). Designed for quick integration with microcontroller projects, the GY521 provides reliable motion and orientation data over a standard I2C interface. Key benefits Precise motion sensing in a small board: combines gyro and accelerometer data for accurate tilt, rotation, and movement detection without needing separate sensors. Easy integration: standard I2C pins and 2.54 mm header layout make wiring to Arduino, Raspberry Pi, ESP, STM32 and other development boards fast and simple. Faster development: widely supported by community libraries (MPU6050 / I2Cdev libraries) and example code, reducing time to prototype. Versatile output options: raw accelerometer and gyroscope data plus access to onchip features such as the MPU6050's digital motion processor (DMP) for sensor fusion when supported by software. What it does (functionality) Measures acceleration on X, Y, Z axes and angular velocity on X, Y, Z axes. Communicates over I2C (SDA, SCL). Device address selectable via AD0 (commonly 0x68 or 0x69). Includes INT (interrupt) pin for dataready or motion interrupt signaling. Exposes standard breakout pins for power, I2C, address selection and interrupt, making it breadboard and shieldfriendly. Key attributes Sensor: InvenSense MPU6050 (3axis gyroscope + 3axis accelerometer). Interface: I2C (SDA, SCL) with AD0 address select and INT interrupt pin. Pinout: typical GY521 headers (VCC, GND, SCL, SDA, XDA, XCL, AD0, INT) on 2.54 mm pitch. Form factor: compact breakout board suitable for breadboard use and small embedded projects. Compatibility: works with Arduino, Raspberry Pi, ESP8266/ESP32, STM32 and other microcontrollers with I2C support; supported by common MPU6050 libraries. Material & build: PCBmounted breakout of the MPU6050 sensor with standard throughhole header pins for prototyping. Performance: provides continuous 3axis acceleration and 3axis angular rate measurements; onchip digital motion processing available for fused orientation data when supported by software. Typical applications (how customers use it) Drone and RC stabilization: provide realtime orientation and rotation data to stabilize quadcopters and multicopters. Robotics and balancing systems: use combined gyro and accelerometer data for selfbalancing robots, gimbals or motor control feedback. Motion sensing and gesture detection: detect tilt, shakes, taps, or orientation changes for wearable devices, game controllers, or interactive projects. Why customers choose this module Single compact module for both accelerometer and gyroscope sensing, reducing wiring and component count. Broad community support and example code accelerate prototyping and debugging. Breadboardfriendly header layout and standard I2C interface for straightforward integration into existing hardware. What to expect in use Fast prototyping with common microcontroller platforms using I2C. Access to raw sensor registers for custom filtering or use of existing libraries to read fused orientation data via the MPU6050's DMP. Simple mounting and wiring: supply power and connect SDA/SCL, optionally use AD0 to change the address or INT for eventdriven reads. Included / typical package GY521 breakout board populated with MPU6050 sensor and standard header pins (Model 1). Notes and compatibility tips Check your development board's I2C voltage levels. The MPU6050 operates with 3.3V logic; many GY521 breakouts are wired to be compatible with common 5V microcontroller Vcc via onboard circuitry—verify the specific board's labeling before connecting 5V directly. Use existing MPU6050 / I2C libraries for faster results; example sketches and community code are widely available. This GY521 MPU6050 Module Model 1 is a practical, widely supported solution for adding 6axis motion sensing to hobby and prototyping projects where compact size and quick integration matter.
