SIM808 GSM/GPRS/GPS IoT Board (Arduino Leonardo Compatible)

Introduction
This is an SIM808 GSM/GPRS/GPS IoT Board based on Arduino Leonardo. The SIM808 with Leonardo mainboard is the latest development board for multi-purpose applications. The onboard SIM808 module includes an integrated quad-band GSM/GPRS and GPS satellite navigation module, and a 4 layer PCB integrates the microcontroller, microphone, headphone jack and GPRS/GPS, giving this board the tiny footprint of a regular credit card! Meanwhile, the board includes a sleep mode feature for extra-low power consumption. And an on-board 3.7V Lipo battery power supply and battery-charging circuit has been integrated into the board, making it ideal for applications such as real-time car tracking, security patrolling, and IoT projects.
Compared with the existing SIM808 modules on the market, this SIM808 uses the latest version with better stability. And it has Bluetooth now.
