Maduino SIM808 + GSM & GPS Module + Antennas

The SIM808 GPS Tracker is an IOT (Internet of things) Solution based on the ATmega328 and GPRS/GSM GPS module. The Arduino Uno Core is integrated on the PCB with the SIM808. The module has also integrated Lipo battery management and charger. Users can program it with Arduino IDE, which is very easy especially suit for the non-programmers.

PLEASE NOTE: a battery is required for the unit - LiPo Battery
