I've bought this I2C LCD interface board NG2 from this seller on eBay.

 

The delivery was in time and the quality of the PCB is OK. But unfortunately the provided library is not working with my board and my LCD display.

The pinout is swapped, means the control and the data lines are swapped, so the library didn't work on the first run.

I've updated the library to handle the control and data lines correctly. You can download the patched library from here. How to use this custom library is described in detail here.

Use it at your own risk!
