GSM SIM800L GPRS TCP IP Module MicroSIM Card

GSM SIM 800L Module GPRS TCP IP Module MicroSIM Card GSM SMS TTL Serial Board With two Antenna

Feature of GSM SIM 800L Module:

Module models: SIM800L (latest module, performance than SIM900)
Operating voltage: 3.7 to 4.2 V (peak current is 2A)
Support network: China mobile, China unicom
Module size: 2.2 x 1.8cm
TTL serial port, can directly link to MCU. Don’t need a MAX232
Power on automatic startup, automatic search network
Onboard one channel indicator light (with signal slow flash, no signal quickly flash)

Arduino Code Sample:

#include <SoftwareSerial.h>

//SIM800 TX is connected to Arduino D8
#define SIM800_TX_PIN 8

//SIM800 RX is connected to Arduino D7
#define SIM800_RX_PIN 7

//Create software serial object to communicate with SIM800
SoftwareSerial serialSIM800(SIM800_TX_PIN,SIM800_RX_PIN);

void setup() {
//Begin serial comunication with Arduino and Arduino IDE (Serial Monitor)
Serial.begin(9600);
while(!Serial);

//Being serial communication witj Arduino and SIM800
serialSIM800.begin(9600);
delay(1000);

Serial.println(“Setup Complete!”);
Serial.println(“Sending SMS…”);

//Set SMS format to ASCII
serialSIM800.write(“AT+CMGF=1\r\n”);
delay(1000);

//Send new SMS command and message number
serialSIM800.write(“AT+CMGS=\”923005930028\”\r\n”);
delay(1000);

//Send SMS content
serialSIM800.write(“TEST”);
delay(1000);

//Send Ctrl+Z / ESC to denote SMS message is complete
serialSIM800.write((char)26);
delay(1000);

Serial.println(“SMS Sent!”);
}

void loop() {
}

Package includes:

1 x SIM800L GSM Module with two antenna and pin headers(Working But Not Register)
