Multiple GY-87 (MPU6050 + HMC5883L + BMP180) connection to arduino

Hi all,

Im fairly new to arduino but i would want to connect 2 GY-87 breakout boards to the same arduino via I2C bus. I have so far figured out that this is simply achieved by pulling AD0 high for the common GY-521 which makes it available on 0x69. But then GY-87 does not have the pinout AD0........any help would be greatly appreciated......

I downloaded this.
There is a schematic showing AD0 (pin 9 of MPU6050) connected to GND.
U can change this by cutting a trace and add a new connection to pin 8 (3.3V)

..or maybe easier to cut pin 9 loose and lift it off the PCB ?
