MPU-6050 GY-521 3-Axis Accelerometer & Gyroscope Module — I2C
The MPU-6050 GY-521 is the most popular 6-DOF IMU (Inertial Measurement Unit) module for Arduino. Combines a 3-axis accelerometer and 3-axis gyroscope in a single I2C module with an integrated Digital Motion Processor (DMP) for onboard sensor fusion. Used in drones, robots, gesture controllers, and balance bots worldwide.
