WHAT IS GSM

•Component provide ::

•.. Short Message Service

•Audio

•GPRS

FEATURE OF GSM

• Fully compatible with Arduino / Freaduino and Mega.

• Free serial port connecting， you can select Hardware Serial port(D0/D1) control or Software Serial port(D2/D3) control it.

• Control via AT commands (GSM 07.07 ,07.05 and EFCOM enhanced AT Commands)

• Supply voltage range : 3.1 … 4.8V

• SIM application toolkit

• Operation temperature: -40°C to +85 °C

• Low power consumption: 1.5mA(sleep mode)

SOFTWARE NEED

• Arduino IDE 1.0.x

• Serial Tool-sscom32

INSTALL GSM HARDWARE

• Hardware Operation

• - Install the SIM card into your GPRS Shield.

• - Take an Arduino board and install the GPRS Shield over it.

• - Connect the antenna to the GPRS Shield.

• - Connect the Arduino to your computer using a USB cable.

• - Plug the power adapter to Arduino.

• - Press and hold the power button a short while(Over 3 seconds) on the GPRS Shield

to turn it on. Wait half a minute for the GPRS Shield to connect to the network (NET

LED will start blinking every 3 seconds or so). If it continues blinking every 800mS,

which means EFCom can’t connect to the Internet, please re-

plug the SIM card and re-plug it., or try another card .
