Detail Premium SIM900 GSM GPRS Shield EFCom Wireless Module SIM 900

Introduction

GPRS Shield-EFCom expansion board is a serial GSM / GPRS wireless module. The purpose is to allow Arduino enthusiast can quickly learn the GSM / GPRS mobile phone development, and can be applied to give the class wireless development projects, but also for the development of various remote control, such as wireless meter reading, intelligent home appliances, ultra-long-range controlWait.

EFCom Freaduino and is compatible with all standard Arduin development board. EFCom is a quad band GPRS / GSM module also supports four standard band 850/900/1800 / 1900MHz , can send SMS text messages, phone calls, faxes and all other mobile phones with GPRS function. EFCom allows you to very quickly understand wireless handset development process and development.

EFCom of three operating modes :
Short Message Service text messaging service mode
Audio Music Mode
GPRS mode
