Description

The SIM808 development board is a comprehensive cellular and GNSS solution built around the SIM808 module. It combines quad-band GSM/GPRS modem capabilities for voice, SMS, and data transmission with an integrated GPS receiver for accurate location fixes. The board is engineered for robust operation across industrial temperature ranges, making it suitable for field-deployed IoT systems.

Communication with a host microcontroller or PC is handled via a TTL-level UART serial interface, programmable through standard AT commands for controlling cellular functions, GPRS data sessions, and GPS NMEA output. The board includes separate SMA and IPX antenna connectors for optimal RF performance on both cellular and GPS bands, and features a dedicated power management circuit supporting a wide input voltage range and direct Li-Ion battery integration.

Key Features

  • Integrated quad-band GSM/GPRS modem and GPS receiver on a single development board.
  • Supports voice calls, SMS messaging, and GPRS data transmission for IoT connectivity.
  • Provides real-time GPS positioning data via NMEA sentences over serial UART.
  • Features dual antenna interfaces (SMA and IPX) for enhanced GSM and GPS signal reception.
  • Includes onboard Li-Ion battery charging circuitry with wide DC input voltage support (5-26V).
  • Designed for low-power operation, suitable for battery-powered tracking applications.

Frequently Asked Questions

How do I communicate with the SIM808 board and send AT commands?

Connect the board's TTL UART TX/RX pins to your microcontroller's serial pins (e.g., Arduino pins 2 & 3 using SoftwareSerial). Power the board with 5-12V, ensure antennas are connected, and open a serial terminal at 9600 or 115200 baud. Send basic AT commands like 'AT' to check communication, then configure the GSM network and GPS using the module's specific AT command set.

What power supply is required, and how do I connect a battery?

The main DC input accepts 5V to 26V, requiring up to 2A if below 9V. For battery operation, connect a 3.5V to 4.2V Li-Ion cell to the dedicated battery terminals; the onboard circuitry manages charging when main power is present. Ensure correct polarity and use a battery with adequate capacity for your project's duty cycle and sleep current requirements.

How do I get GPS location data from the SIM808 module?

Enable the GPS receiver by sending the AT command 'AT+CGPS=1'. The module will start acquiring satellites. Once fixed, you can retrieve NMEA data (e.g., GGA, RMC sentences) directly from the serial interface or request parsed coordinates using commands like 'AT+CGPSINFO'. Ensure the GPS antenna has a clear view of the sky for optimal signal reception.
