What You'll Get

The SIM808 with Leonardo mainboard is the latest Arduino board developed by DFRobot 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.
