VCC supplies power to the module.

GND is the ground pin.

SCL is a serial clock pin for the I2C interface.

SDA is a serial data pin for the I2C interface.

XDA is the external I2C data line. The external I2C bus is for connecting external sensors, such as a magnetometer.

XCL is the external I2C clock line.

AD0 allows you to change the I2C address of the MPU6050 module. It can be used to avoid conflicts between the module and other I2C devices or to connect two MPU6050s to the same I2C bus. When you leave the ADO pin unconnected, the default I2C address is 0x68_HEX; when you connect it to 3.3V, the I2C address changes to 0x69_HEX.

INT is the Interrupt Output pin. The MPU6050 can be programmed to generate an interrupt upon detection of gestures, panning, zooming, scrolling, tap detection, and shake detection.

Wiring an MPU6050 Module to an Arduino

Let’s hook the MPU6050 module to the Arduino.

Connections are straightforward. Begin by connecting the VCC pin to the Arduino’s 5V output and the GND pin to ground.

Now we are left with the pins that are used for I2C communication. Note that each Arduino board has different I2C pins that must be connected correctly.  On Arduino boards with the R3 layout, the SDA (data line) and SCL (clock line) are on the pin headers close to the AREF pin. They are also referred to as A5 (SCL) and A4 (SDA).

Check out the table below for quick reference.

The diagram below shows how to connect everything.
