SIM808 GSM/GPRS/GPS Developement Board (Compatible with Arduino and Raspberry Pi)

SIM808 GSM/GPS Development Module

The development board equipped with a SIM808 module enables you to use GSM communication and GPS features with your development boards like Arduino and Raspberry Pi. With this board, you can send and receive SMS, track location, and even create your own cell phone! The SIM808 module on the board is responsible for the GSM communication and GPS receiver functions. The board can be powered by a 5-26VDC power source or battery (it is recommended to use a power source that can provide a minimum of 2A current at voltages lower than 9V). Alternatively, you can use single cell (1S) Li-Po or Li-Ion batteries (such as 18650) by using the lithium battery connection on the board (accepts voltage between 3.5-4.2V). The board has SMA connectors for antenna connections. Separate antennas are required for GSM, GPS, and Bluetooth. To start the board, you need to press and hold the "start" button for 2 seconds after connecting the power. You can see the network connection status of the board from the LEDs on it. The board has a 1.25V/3.3V/5V compatible TTL serial connection (UART) for connecting to development boards like Arduino and Raspberry Pi.
