Product Description

This is an Arduino Mega Shield for SM5100 quad-band GSM/GPRS module. The module is included.


Due to the large current of the GPRS module, a wall adaptor is recommended:








Jumpers position:

J1: 5100RX to TX1

J2: 5100TX to RX1



Pass through code:

#include         //Used for string manipulations

char incoming_char=0;      //Will hold the incoming character from the Serial Port.

void setup()


  //Initialize serial ports for communication.



Serial.println("Starting SM5100B Communication...");


void loop()


//If a character comes in from the cellular module...

if(Serial1.available() >0)

{;    //Get the character from the cellular serial port.

Serial.print(incoming_char);  //Print the incoming character to the terminal.


//If a character is coming from the terminal to the Arduino...

if(Serial.available() >0)

{;  //Get the character coming from the terminal

Serial1.print(incoming_char);    //Send the character to the cellular module.
