AD0 (If this pin is LOW, the I2C address of the board will be 0圆8.

XCL (Auxiliary clock => I2C master serial clock for connecting the module to external sensors.).

XDA (Auxiliary data => I2C master serial data for connecting the module to external sensors.).

SDA (Serial Data Line of the I2C protocol.).

SCL (Serial Clock Line of the I2C protocol.).

Therefore, you can connect the board to 3.3V and 5V sources.)

VCC (The breakout board has a voltage regulator.

Please follow this link to find an excellent library with many examples. If you plan to use the full range of features or require reliable and stable position data, then I recommend to have also a look at ready-to-use libraries. The sensor values are retrieved by using the I2C serial data bus, which requires only two wires (SCL and SDA). In particular, it is shown how to retrieve the raw sensor values. This tutorial gives only a brief introduction to the GY-521/MPU-6050. Usually, the DMP processes algorithms that turn the raw values from the sensors into stable position data.

The digital motion processor can be used to process complex algorithms directly on the board. The GY-521 module is a breakout board for the MPU-6050 MEMS (Microelectromechanical systems) that features a 3-axis gyroscope, a 3-axis accelerometer, a digital motion processor (DMP), and a temperature sensor.
