SIM808 GPS Tracker v1.5 user manual
Version: v1.5
Editor: Sam
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.
