Description

The SIM808 Bluetooth Compatible GSM/GPRS/GPS Module is a comprehensive development platform centered on the SIM808 system-on-chip, merging global 2G cellular communication, satellite navigation, and short-range wireless connectivity. It operates across all standard GSM frequency bands, enabling SMS, GPRS data transmission, and voice calls, while its integrated MT3337 GPS receiver delivers precise location tracking with cold-start sensitivity as low as -148dBm. The board is engineered for robust IoT system integration, featuring dual antenna ports (SMA and IPEX) for flexible RF deployment and a wide-input voltage regulator supporting direct DC or lithium battery power for field deployments.

Designed for developers and system integrators, the module provides a single UART serial interface with automatic baud rate detection, allowing seamless switching between GSM and GPS functions via AT commands. Its compact form factor, extended operating temperature range (-40°C to 85°C), and included GPS/GSM antennas make it suitable for building asset trackers, remote telemetry units, portable navigation devices, and emergency communication systems using popular platforms like Arduino IDE or Raspberry Pi.

Key Features

  • Unified GSM/GPRS and GPS module with Bluetooth support for multi-protocol IoT connectivity.
  • High-performance MT3337 GPS chipset with 22 tracking / 66 acquisition channels and fast TTFF.
  • Quad-band GSM/GPRS Class 12/10 support ensures global 2G network compatibility for data and SMS.
  • Comprehensive voice call capability with onboard electret microphone and 32-ohm speaker driver outputs.
  • Flexible power management with wide 5-26V DC input and dedicated Li-ion battery connector for portable use.
  • Dual antenna interface options (SMA and IPEX) for both external and embedded antenna installations.
  • Extended industrial temperature range operation from -40°C to 85°C for harsh environment reliability.
  • Direct UART serial control with automatic baud rate detection and full AT command set support.

Applications

  • Asset Tracking & Fleet Management: Real-time GPS location reporting via GSM SMS or GPRS data.
  • Remote Environmental Monitoring: Field data loggers transmitting sensor readings over 2G networks.
  • Personal Safety & Emergency Devices: Panic button systems with location alerts and voice call capability.
  • Smart Agriculture: Livestock tracking and irrigation system control with cellular backhaul.
  • Portable Navigation & Messaging Devices: DIY handheld communicators for outdoor activities.

Frequently Asked Questions

How do I power the SIM808 module and connect it to an Arduino?

Supply 5-26V DC to the board's DC jack or use a 3.7V Li-ion battery on the dedicated terminals. For UART communication, connect the module's TXD pin to your Arduino's RX pin, RXD to TX, and share a common GND. Use a logic level converter if your Arduino operates at 3.3V. Insert a valid 2G SIM card, attach the included antennas, and press the POWKEY button for 2 seconds to start. Communication is via AT commands sent over the serial connection.

What AT commands are used to get GPS location data via the SIM808?

First, enable the GPS power with AT+CGPSPWR=1. To start the GPS engine, use AT+CGPSRST=0. Wait for a fix, then query the raw NMEA data with AT+CGPSINF=0 or get parsed latitude/longitude using AT+CGPSINF. For GPRS data transmission, establish a TCP connection with AT+CIPSTART="TCP","server.com",port, then send data with AT+CIPSEND. Always ensure the GSM antenna has good signal strength, indicated by the network status LED, before attempting data transfers.

Can I use this module for SMS alerts and voice calls in my project?

Yes. For SMS, use AT+CMGF=1 to set text mode, then AT+CMGS="+1234567890" to send a message. End the message content with Ctrl+Z (0x1A). For receiving SMS, configure the module with AT+CNMI=2,1,0,0,0. Voice calls require connecting an external electret microphone and a 32-ohm speaker. Initiate a call with ATD+1234567890; and answer with ATA. The board provides the necessary audio interface pins. Ensure your SIM card has call and SMS services enabled from your carrier.
