Description

SIM808 GPS Tracker is an IOT (Internet of things) Solution based on the ATmega328 and GPRS/GSM GPS module SIM808. It intergrate a micro Controller Atmega 328, GRRS/GSM module SIM808, which is the 
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.
