Need Help Interfacing an Uno with the grid eye sensor

I have ordered an evaluation kit for the grid eye sensor and i can't seem to get it to interface with my uno using I2C .
I used a sparfunk breakout before and it seemed to work perfectly with their libraries but i can't do the same with the eval kit .

this is the product

and this is the manual it came with

any help with i2c communication with the uno please .

Isn't it a 3.3V only device?

Mine works fine with a Sue.
