The module with SIM 808 chip is used for communication in the GSM / GPRS standard. It also has the ability to communicate with Bluetooth and read the current GPS position. There are two 3.5 mm Jack sockets on board for connecting headphones and a microphone for making cellular phone calls. The board has an integrated vibration module that is activated during incoming phone calls. The SMA antenna sockets on the module are used to connect external GSM, GPS and Bluetooth antennas. The set includes GSM and GPS antennas. The module has all the pins necessary to configure the SIM 808 chip using AT commands and to transmit and receive GPRS, GSM and Bluetooth data. There is a SIM card slot on the back of the module. Communication with the module takes place via UART bus which, thanks to the voltage converters on the module, can work in the TTL (5V) standard. The module is powered by the DC 2.1 / 5.5 socket. The micro USB socket on the module is used to update the firmware of the SIM 808 system. The module comes with two antennas: GPS and GSM.

The module's power supply is in the range of 5 - 26VDC, current consumption is 2A and this power must be secured, otherwise the module may not log on to the GSM network.

Pin description:

- RXD, TXD - UART bus used for configuration and control of the SIM 808 system using AT commands and for data transmission.
- VMCU - pin used to set the high level of the UART bus. If we want to control the module using a device with a UART 5V bus level (e.g. ATmega32 processor), then this pin is given a voltage of 5V.
- LI-ion - pins for connecting a lithium battery, e.g. 18650

Quick way to start the module:

We connect the voltage in the range 5 - 26V to the DC socket. Set the main switch to the ON position. Press and hold for about 3 seconds the button marked on the module as POWKEY. After releasing the button, the module will be started, which will be signaled by the corresponding LED diodes on the module lighting up.
