SIM800C GPS

Using Arduino Networking, Protocols, and Devices
1

Hi, new member here.

I'd like to interface a SIM800C to an Arduino UNO as a tracking device whereby upon receipt of a text/sms the Arduino responds with a GPS location.

I have found there are 2 types of SIM800 boards on eBay and would like to ask are there any major differences between them that would make either one unsuitable for the above project.

I can post ebay links but wasn't sure external url's are allowed on this forum so I will just quote the listing numbers.

The 2 examples are ebay item 192523454861 and item 263774597312. Is the *312 item a simplified version of the *861 ? And will the larger antenna on the *861 make it easier to connect to the GPS signal ?

Apologies for a basic question, as I said I am a newbie to Arduino

thank you

Hi, here are the 2 boards I mentioned in my 1st post

If anyone can explain what the differences are, thanks
