Introduction

SIMduino is a IoT panel based on the Arduino Uno board (click here for more information of Arduino Uno) and SIM808, ATmega328 is the microcontroller and GPS module is based on SIM808, SIM808 supports GPS, GPRS and Bluetooth, as you can see, it can be used to transmit/receive short message, give/answer a call, connect computer and exchange files through Bluetooth and realize the function of satellite navigation.
