Main features of the communication module

  • Communication protocol support: TCP / UDP / HTTP / HTTPS / TLS / DTLS / PING / LWM2M / COAP / MQTT
  • Positioning functions: GNSS supports GPS, GLONASS, BeiDou and Galileo
  • Standard 40-pin GPIO connector: compatible with Raspberry Pi series
  • Leaded UART pins: for connection to development boards, e.g. Arduino / STM32
  • Global LTE bands: NB-IoT and Cat-M with wide coverage
  • Low power consumption: power saving modes like PSM and eDRX
  • AT Commands Support: for configuration and testing
  • Built-in USB interface: for testing AT commands, obtaining GPS positioning data and other functions
  • Built-in voltage translator: 3.3V default, switchable to 5V via jumper
  • SIM card slot: Only supports 1.8V SIM cards (3V SIM cards not supported)
  • 3 LEDs: for easy monitoring of the working status
  • Data transfer rate: 300 to 3686400 bps
  • Auto-negotiation of popular baud rates: 9600 / 19200 / 38400 / 57600 / 115200 bps

Compatibility and module connection

The module is compatible with popular microcontrollers such as Raspberry Pi , Arduino , and STM32 . The module connects directly to the Raspberry Pi to the 40-pin GPIO connector. In the case of Arduino, pins D10 (RX) and D11 (TX) are used for serial communication, and for STM32, UART pins . In order to connect the module correctly, you must also connect the LTE and GPS antennas , and make sure that the SIM card is compatible (only 1.8 V). The module is turned on by holding the PWRKEY button for about 1 second.

The module does not support standard SIM cards . You must use an NB SIM card or a SIM card that supports eMTC.

Raspberry Pi is not included in the kit. The minicomputer can be purchased separately.

Module programming

The module is programmed using AT commands , which are sent via the serial port. For example, to connect to the network, you can use commands such as AT+CPIN? (checking the SIM card) or AT+CNMP=38 (setting the LTE mode). For Raspberry Pi, you can use the Python library , the sample code of which can be downloaded from a dedicated repository. Programming on Arduino and STM32 involves sending AT commands from the appropriate programming environment (IDE) , according to the module documentation.

Attention!

The SIM7080G supports global frequency bands, so there may be delays when registering on the network.
