what is the diffrence between 5 VDD and 12V on this pin out diagram
Looks to me like it has a switching power supply and can operate from either 5V or 12V. It's likely it might work okay on other (intermediate) voltages but it's not specified for operation other than at 5.0V+/-10% or 12.0V+/-10%. From the data:

That said, I would have a gander at the PCB near the input power connector and switching power supply circuitry to see if there is some kind of jumper or something like that before applying 12V to the module. That's in the upper left of the PCB photo and I see nothing but the photo is quite blurry.
