I found it, It's an ebay item (number 271040846018) , on the product page is a link to the data sheets - look at P2 - Rx and Tx are there, remember to connect the grounds, power the unit from an external PSU.

Thanks a lot for your response.

I have downloaded the datasheet but I couldn't find the RX and TX. What did you mean by "look at P2 " ?

As I have mentioned before, I'm a newbie could you please explain me in detail?

Regards,

Can you take a photo of the sim board from the top, so I can see the labels on the headers please.

Please find the attached file which contains two photos of top and bottom sides of the sim board.

Thanks in advance.
