  • SIM900 GPRS/GSM Shield Development Board Quad-Band Module For Arduino Compatible High Quality ()

    The GPRS Shield is based on SIM900 module from SIMCOM and compatible with Arduino and its clones. The GPRS Shield provides you a way to communicate using the GSM cell phone network. The shield allows you to achieve SMS, MMS, GPRS and Audio via UART by sending AT commands (GSM 07.07 ,07.05 and SIMCOM enhanced AT Commands). The shield also has the 12 GPIOs, 2 PWMs and an ADC of the SIM900 module(They are all 2V8 logic) present onboard.


    Quad-Band 850 / 900/ 1800 / 1900 MHz - would work on GSM networks in all countries across the world. 
    GPRS multi-slot class 10/8
    GPRS mobile station class B
    Compliant to GSM phase 2/2+
    Class 4 (2 W @ 850 / 900 MHz)
    Class 1 (1 W @ 1800 / 1900MHz)
    Control via AT commands - Standard Commands: GSM 07.07 & 07.05 | Enhanced Commands: SIMCOM AT Commands.
    Short Message Service - so that you can send small amounts of data over the network (ASCII or raw hexadecimal).
    Embedded TCP/UDP stack - allows you to upload data to a web server.
    RTC supported.
    Selectable serial port.
    Speaker and Headphone jacks
    Low power consumption - 1.5mA(sleep mode)
    Industrial Temperature Range - -40°C to +85 °C

  • SIM808 Module GSM GPRS GPS Development Board SMA With GPS Antenna For Arduino ()


    1.Three power input interface: DC044 interface and V_IN and a lithium battery interface.
    Note that: The range of DC044 and the V_IN pin voltage input is 5 - 26V, when use the 5V as the power, be sure that the power supply can provide 2A current. The range of voltage of Lithium battery input power is 3.5 - 4.2V.
    2. Switch: It is used to open / close the input power supply for the module. When in use, please confirm the toggle switched to the OPEN state (near the board inside).
    3. SMA antenna interface: there is a GSM antenna interface, a GPS antenna interface onboard and a BT antenna interface.
    4. Start button: When the board is power on, the LED (PWR) will light up. After a long press (about 2 second) on this button, the other three LEDs will be light. And one of them starts to flash; this suggests that SIM808 is beginning to work now. When the power supply, GSM and GPS antenna and SIM card are connected to the module correctly, the LED will be flash slowly (3Second de 1second light), that indicates that the module is registered to the network, and you can make a call or do something else.
    5. TTL serial interface: a TTL level interface. Notice that: The pin of VMCU is used to control the high level of TTL UART, so as to realize to match between 1.25V/3.3V /5V systems. For example, if you want to use the 51 MCU to control this board, the pin of VMCU should be connected the DC5V. And if use the STM32 MCU, the pin of VMCU should be connected the DC3.3V. The pins of RXD is the RXD of SIM808 and the pins of TXD is the TXD of SIM808. The pin of V_IN can connect the Power, the function of this pin has the same function of DC044.
    6. USB interface: This interface is just use to update the firmware of SIM808 module.
    Operation Description:
    1. Preparation:
    DC9V adapter
    USB-TTL module or other tools.
    PC software
    2. Hardware configurations
    2.1 Connect the USB-TTL to the UART interface
    USB-TTL SIM808
    2.2 Insert the valid SIM card to the SIMCARD holder.
    2.3 Connect the GPS antenna and GSM antenna to the board
    Connect the power adapter to the DC044 Interface
    2.4 Change the switch
    2.6 Press the POWKEY button for 2 second, the SIM808 module will work and the other 3 LEDs will light.
    Package Included:
    1 X SIM808 Moudle
    1 X GSM Antenna
    1 X GPS Antenna
