SIM808 Arduino GPS/GPRS/GSM Shield

The SIM808 GPS/GPRS/GSM Shield is an integrated quad-band cellular and GPS navigation shield for Arduino. Compatible with Arduino Uno, Leonardo, Mega, and other standard-footprint boards, it provides SMS, voice calls, GPRS data, MMS, and GPS positioning in a single compact module. A dedicated Arduino library simplifies development without needing to work directly with AT commands.
