I got my hands on a GSM module and apart from the labeling on the connectors, I have not been able to find a data sheet of any kind. It is unmarked and I have tried and tried, but I am not able to find any information. The only marking is SK1_modem.

Since I was not able to make much of the information given to me on , I was hoping that someone might have an idea on how to connect the 10 pins to my arduino and get the module to work. I tried reverse-engineering some of the GSM shields online but was not able to get anywhere...

I have started to read about AT commands since it seems like I will be needing those.

They are labeled as follows:

1 - VBAT
2 - P1.2/RXD2/GSMTX
3 - P1.3/TXD2/GSMRX
4 - PCTX/GSMRX
5 - PCRX/GSMTX
6 - GSMRESET
7 - GSMONOFF
8 - INT1_MODEM
9 - GND
10 - SDA/GSMDATADTR


Any tips and guidance would be greatly appreciated!

Thanks in advance.
