Description
The SIM808 Development Board is a high-performance, all-in-one communication solution designed for the Internet of Things (IoT). This board integrates Quad-Band GSM/GPRS technology with a high-sensitivity GPS receiver into a single, compact package. Featuring the latest upgraded chip version, it offers superior stability and lower power consumption compared to previous iterations.
Engineered for seamless integration with STM32, Arduino, and 51-series microcontrollers, this board is the perfect core for vehicle tracking, remote environmental monitoring, and smart security systems. Whether you are a developer building a single prototype or a business purchaser sourcing components for fleet management hardware, the SIM808 provides the robust cellular and satellite connectivity required for modern “connected” projects.
Key Features
  • Triple Functionality: Combines GSM (Voice), GPRS (Data), and GPS (Location) on a single board, reducing the physical footprint of your project.
  • IoT Ready: Optimized for low-power M2M (Machine-to-Machine) applications and remote data transmission.
  • New Chip Version: Features improved GPS acquisition sensitivity and more stable network handovers in weak signal areas.
  • Multi-Platform Support: Fully compatible with STM32, Arduino, and Raspberry Pi via standard TTL serial communication.
  • Onboard Power Management: High-current LDO supports a wide input voltage range while handling the high-current peaks required during GSM transmission.
  • Antenna Interfaces: Includes dedicated IPX or SMA connectors for both GSM and GPS antennas to ensure maximum signal gain.
Usage Instructions
  1. Antenna Connection: Securely attach both the GSM and GPS antennas before powering the device. Operating without antennas can damage the RF circuit.
  2. SIM Card Insertion: Insert a valid Micro SIM card with GPRS data and SMS services enabled.
  3. Power Supply: Connect a 5V power source capable of providing at least 2A of current. The module requires high current bursts when searching for a network.
  4. Wiring to MCU: Connect the TXD and RXD pins of the SIM808 to your microcontroller’s UART pins. Ensure a common Ground (GND) connection.
  5. Commands: Use standard AT Commands to initialize the GSM network and NMEA protocols to read GPS coordinate data
Q: Can I use this for real-time vehicle tracking?

Yes. The SIM808 is specifically designed for tracking. It can capture GPS coordinates and send them to a server via GPRS or via SMS to a mobile phone.

Q: Does it work on modern 4G or 5G networks?

No, the SIM808 operates on 2G (GSM/GPRS) networks. Please ensure your local service provider supports 2G/GSM in your region before purchasing for large-scale deployment

Q: Why is the GPS LED not blinking or getting a "fix"?

GPS signals are weak and usually cannot penetrate indoor ceilings. Ensure the GPS antenna has a clear, unobstructed view of the sky. Initial “Cold Start” positioning may take 30–60 seconds

Q: Is this board suitable for commercial IoT products?

Absolutely. The “New Chip Version” is selected for industrial reliability. It includes overvoltage protection and high-quality tantalum capacitors for long-term stability in commercial environments

Q: How do I interface this with an STM32 or Arduino?

The board uses standard TTL levels. You can use the Serial library in Arduino or the USART peripheral in STM32. Most developers use established libraries (like TinyGSM) to simplify the coding process
