The SIM808 GPS/GPRS/GSM Arduino Shield is a compact quad-band GSM/GPRS and GPS navigation technology Arduino shield that is the size of a credit card. This shield is compatible with various mainboards including the Arduino UNO, Arduino Leonardo, Arduino Mega, and others. Compared to the previous generation SIM908, SIM808 has improved performance and stability. Besides the basic SMS and phone functions, the shield also supports advanced features such as MMS, DTMF, FTP, and more. With this shield, you can acquire data, transmit wireless data, develop IoT applications, and use GPS for orientation.

What’s it for:

• Send and receive GPRS data (TCP/IP, HTTP, etc.)
• Receive GPS data and A-GPS data
• Send and receive SMS messages
• Make and receive phone calls

Using the SIM808 Arduino shield is quick and easy. With intuitive functions packaged into a single library, you can focus on your project and not waste time studying complex AT commands.
