I recently bought a cheap GY-521 gyro sensor from a local store to experiment with a quadcopter. I couldn't find any programs to test this directly, other than some links that told me to run a MPU-6050 code reading values from the I2C bus.
When I read the values from the I2C bus, I am apparently able to get Gyro, Accelero and Temp values. I used the program for MPU 6050 from here - MPU6050 gyro.
So is this just a cheap version of MPU6050?
