The I2C interface module works fine on my blue 1602 LCD module. The I2C address is 0x27 out of the box so remember to modify your code accordingly. There is a very clear description that can be found here: http://arduino-info.wikispaces.com/LCD-Blue-I2C. It clearly describes the different available versions of the I2C interface. The one I received was version 3. When I first connected it and run the sample code I adjusted for the 16x2 display it did not seem to show any information on the display. The root cause was the potentiometer on the I2C interface not to be setup correctly out of the box. I needed to adjust it to change the contrast and show the characters on the screen. So I am happy with this interface as it reduces the connection to only 4 wires (2 for the power supply and 2 for the communication).
