Interfacing SIM900A V5.1 Module

Using Arduino Project Guidance
#1

I am unable to figure out the pins in the SIM900A V5.1 Module. I need those pin details. Can I directly connect to the arduino using SoftwareSerial?

Have only seen V4.0 or V6.1 boards for sale, as spycatcher says you need to give us a link to that 5.1 board.

Are you aware the Sim900A only works in certain far east countries ? though you can reprogram the firmware; it might be simpler to use a Sim900 or Sim800 module instead.

The SIM900A-model is locked to these regions:

China
India
Singapore
Malaysia
Thailand
Indonesia
Cambodia
Vietnam
Laos
Burma
Brunei
Philippines
East Timor

Seems those boards are either very new to to open market or a lesser design going cheap.

Cannot see anywhere giving details of the output connector pinout, though one of those links says it comes with a user manual.

Unless someone else has his board and knows the pinout, think you need to contact the seller for the details.
