Refurbished SIM900A GPRS Module

This Refurbished SIM900A GSM Moduleis the smallest and cheapest module for GPRS/GSM communication. It is common with Arduino and microcontrollers in most embedded applications. The module offersGPRS/GSM technologyfor communication with the use of a mobile sim. It uses a900and1800MHzfrequency band and allows users to receive/send mobile calls and SMS. The keypad and display interface allows the developers to make customized applications with it. Furthermore, it also has modes, command mode and data mode.TheModule SIM900Alooks like a single chip, but it has a bunch of features that can help to build almost many commercial applications. Although there are a total of 68 pins on SIM900A and using these pins helps to build the applications. But we will need a few pins if you use a module for interfacing with Arduino.
