SIM900A RS232 for PC or TTL microcontroller interface with DTMF active feature. The GSM/GPRS Cellular Module for Microcontrolles/ Embedded Systems/ Home automation is complete in all respect ready to plug-in interface for your microcontroller(Arduino,Raspberry pi, Atmega, PIC, Basic Stamp, 8051, AVR etc) with an SIM900A GSM/GPRS cellular module. This allows you to easily add SMS, GSM/GPRS, and TCP/IP functionalities to your microcontroller based project. Dual Mode fuctionality - connect with RS232 serial port for direct PC interface or through TTL I/O interface for microcontroller based autonoumous projects.
All you need to add cellular functionality to your project is a SIM card (pre-paid or straight from your phone) and you can start sending Serial messages to make calls, send texts and serve web pages!
