Maduino SIM808 GPS Tracker

It intergrate a micro Controller Atmega 328, GRRS/GSM module SIM808, which is the 

SIM808 GPS Tracker is an IOT (Internet of things) Solution based on the ATmega328 and GPRS/GSM GPS module SIM808. 

upgrade version of SIM900, power management and storage, to make the SIM808 GPS Tracker ready for real project for IOT projects such as smart-home, outdoor monitoring, shared bicycle, etc.

The SIM808 GPS Tracker based on the Arduino, users can program it with Arduino IDE, which is very easy  especially suit for the none-programmers. There are also guide for users to learn how to create the first  IOT project with this board, with which the starters can learn the hardware and programming skill quickly.
