SIM808 Moudle with Antenna 5-26V DC044 interface GSM GPRS GPS Development Bureau SMAW/ GPS Antenna for Arduino

"describe:

1. Three power input interface: DC044 interface and V_IN and lithium battery interface.

It should be noted that the voltage input range of DC044 and V_IN pins is 5-26V. When using 5V as a power supply, make sure that the power supply can provide 2A current. The voltage range of lithium battery input power is 3.5-4.2V.

2. Switch: Used to turn on/off the input power module. When in use, please make sure to switch to the OPEN state (near the board).

3. SMA antenna interface: There is a GSM antenna interface, GPS antenna interface, onboard and BT antenna interface.

4. Start button: When the motherboard is powered on, the LED indicator (PWR) will light up. After pressing this button for a long time (about 2 seconds), the other three LEDs will light up. One of them starts to flash; this indicates that SIM808 has started to work until now. When the power supply, GSM and GPS antennas and SIM card are correctly connected to the module, the LED will flash slowly (3 second generation 1 second light), indicating that the module is registered on the network, and you can make calls or do other things.

5. TTL serial interface: TTL level interface. Please note: VMCU pin is used to control the high level of TTL UART in order to achieve a match between 1.25V / 3.3V / 5V systems. For example, if you want to use 51 single chip microcomputer to control this kind of board, the pin of VMCU should be connected to DC5V. If STM32 microcontroller is used, the pin of VMCU should be connected to DC3.3V. The pin of RXD is RXD of SIM808 and the pin of TXD is TXD of SIM808. The pin of V_IN is connected to the power supply, and the function of this pin is the same as that of DC044.

6. USB interface: This interface is only used to update the firmware of the SIM808 module.
