Introduction
SIM808 GPS/GPRS/GSM arduino shield (https://www.dfrobot.com/product­1469.html) is an integrated quad­band GSM/GPRS and GPS navigation technology
Arduino expansion shields. A credit card size only, according to the standard Arduino pin packaging, compatible with Arduino UNO
(https://www.dfrobot.com/product­1468.html), arduino Leonardo (https://www.dfrobot.com/product­698.html), arduino Mega (https://www.dfrobot.com/product­
358.html) and other arduino mainboard (https://www.dfrobot.com/category­104.html).
Compared to the previous generation SIM908, SIM808 made some improvement on the performance and stability. In addition to the normal SMS and phone
functions, the shield also supports MMS, DTMF, FTP and other functions. You can achieve the data acquisition, wireless data transceiver, IoT application and GPS
orientating. The should integrates onboard microphone and headphone jack, saving your cost and making your project easily. it can also directly connect to the
GSM and GPS antenna by an external antenna connector.
SIM808 GPS/GPRS/GSM Arduino Shield V1.0 uses the latest version of Simcom SIM808 module, compared with the early SIM808 module available in the market,
the new module has better stability. But GPS part of AT commands are not compatible with the old version of the SIM808 module, please refer to the bottom of the
"more" in the AT commands.
