DESCRIPTION

The Shield GPRS/GSM SIM900 is the easiest way to connect your Arduino projects to the cellular network and thus be able to send and receive text messages (SMS), voice calls and even connect to the Internet via GPRS and thus enter the world of the Internet of things (IoT). The Shield SIM900 works in the 850/900/1800/1900MHz GSM bands. All you need to add cellular functionality to your project is a SIM card (Entel, Movistar or Claro) and now you can start sending messages, making calls, among others.

The main chip of the Shield is the SIM900: a low cost GSM/GPRS modem with extensive support. The SIM900 supports AT commands by Serial UART, by using the commands it allows to send and receive SMS, make calls and connect to the Internet. In Arduino we can use a software serial port on pins D7 and D8, use the hardware Serial port on pins 0 and 1 or directly use the USB-Serial converter of the Arduino board using pins D0 (TX) and D1 ( RX). The Shield has two jumpers that allow you to select the pins for serial communication.

Using the Shield SIM900 GSM / GPRS with Arduino is very simple. First we must insert a SIM card in the corresponding socket and then we can directly mount the shield on an Arduino Uno. To power the shield we have 2 options that can be selected by means of an on-board switch: power the shield from our Arduino or with an independent source. If we choose an external or independent source we recommend using sources between 9V to 12V DC and that can supply currents greater than 1 amp, the  9V source for Arduino it's a good option. To activate the Shield we can do it manually or by software, manually with the on-board button and by software with Pin D9 (we must previously solder the PWR pads). The Shield includes an antenna with SMA connector, but if we want to make an extension of the location of the antenna we can choose one of these antennas: Linear GSM antenna with IPEX connector or GSM antenna with IPEX connector . The Shield SIM900 is perfectly compatible with Arduino Uno and Leonardo, to work with Arduino Mega we must wire pins D7 and D8 to pins RX1 and TX1.

NOTES

  • The SIM900 Board Input is 5-26V 2A,We Recommended current is more than 9V 2A. Ensure your SIM card is not locked GPRS Communication baud rate is 19200 BPS 8-N-1.

FEATURES

  • The GPRS Shield provides you a way to communicate using the GSM cell phone network.
  • The GPRS Shield is based on SIM900 module from SIMCOM and compatible with Arduino and its clones.
  • The shield also has the 12 GPIOs, 2 PWMs and an ADC of the SIM900 module (They are all 2V8 logic) present on board.
  • The shield allows you to achieve SMS, MMS, GPRS and Audio via UART by sending AT commands (GSM 07.07 ,07.05 and SIMCOM enhanced AT Commands).
  • This module power supply for: 5V~26V, if more than 5V power supply must be in 2A, recommend a 9V power supply. Plug in the Arduino motherboard, power supply must be able to provide 2A current.
