SIM900 GSM/GPRS Shield for Arduino

Instantly add cellular connectivity to your Arduino projects with the SIM900 GSM/GPRS Shield. This powerful shield plugs directly onto your Arduino Uno or Mega, making it incredibly simple to send/receive SMS messages, make/receive phone calls, and connect your project to the internet over the 2G GPRS network.

Based on the reliable SIM900 quad-band GSM module from SIMCom, this shield is a complete communication solution. It features an onboard SIM card holder, a robust SMA antenna connector, and 3.5mm jacks for connecting a microphone and speaker to utilize its voice call capabilities. The shield includes all necessary level-shifting circuitry, allowing it to interface safely with your Arduino.

A dedicated DC barrel jack allows you to provide a stable, external power supply, which is essential for the high-power demands of cellular communication. With the help of the readily available Arduino libraries, you can get your remote sensor, SMS alert system, or IoT device up and running in minutes.

Key Features:

• Easy Integration: Plugs directly on top of Arduino Uno, Mega, and compatible boards.
• Chip: SIMCom SIM900 Quad-Band (850/900/1800/1900 MHz)
• Core Functions: SMS, Voice Calls, GPRS (TCP/IP), DTMF
• Audio Interface: Onboard 3.5mm jacks for external microphone and speaker.
• Power Supply: DC barrel jack for required external power (5V-12V recommended).
• SIM Card Slot: Full-Size SIM Holder.
• Antenna: SMA connector with included “Rubber Ducky” Antenna.

Applications:

This shield is perfect for a wide range of Arduino-based projects, including remote equipment control, home automation SMS alerts, vehicle tracking, remote weather stations, and any IoT application that requires a simple and effective cellular communication link.
