Description

The SIM808 module from SIMCom is a highly integrated system-on-chip (SoC) solution designed for developers requiring both GSM/GPRS cellular communication and GPS satellite navigation. It leverages the latest SIM808 chipset, providing a compact footprint ideal for space-constrained IoT devices like asset trackers, fleet management systems, and remote telemetry units. The module’s architecture supports full AT command control, enabling seamless integration with microcontrollers like Arduino, ESP32, or STM32 for custom firmware development.

Engineered for industrial reliability, the SIM808 operates across an extended temperature range from -40°C to 85°C, ensuring performance in harsh outdoor or vehicular environments. Its power system is optimized for low-power modes, crucial for battery-operated tracking applications. The integrated GPS receiver operates on the L1 C/A frequency, offering rapid time-to-first-fix (TTFF) and continuous tracking capabilities, while the GSM transceiver ensures stable network registration and data session management across global quad-band networks.

Key Features

  • Dual-Function Chipset: Integrates a complete GSM/GPRS modem with a standalone GPS receiver, reducing board space and BOM cost.
  • Quad-Band GSM/GPRS: Provides global cellular coverage on 850/900/1800/1900 MHz bands for reliable connectivity.
  • High-Performance GPS: Features 22 tracking and 66 acquisition channels with -165 dBm sensitivity for accurate positioning in urban canyons and rural areas.
  • Comprehensive Data Protocols: Supports GPRS Class 12, CSD, PPP stack, and USSD for versatile data, voice, and SMS applications.
  • Bluetooth Coexistence: Integrated Bluetooth 3.0+EDR allows for local device pairing, configuration, and short-range data transfer.
  • Industrial-Grade Durability: Rated for operation from -40°C to 85°C, suitable for automotive, logistics, and outdoor IoT deployments.
  • Developer-Friendly: Controlled via standard AT commands, with extensive documentation and community support for rapid prototyping.

Applications

  • Vehicle Tracking & Fleet Management: Real-time GPS location reporting via GPRS/SMS for logistics and transportation.
  • Asset Tracking & Security: Monitors high-value cargo, equipment, or containers with cellular data backhaul.
  • Personal Safety Devices: Used in wearable SOS locators and emergency beacons with two-way communication.
  • Remote Environmental Monitoring: Transmits sensor data (temperature, humidity) from field sites using GPRS connectivity.
  • Smart Agriculture: Enables tracking of agricultural machinery and monitoring of remote irrigation systems.

Frequently Asked Questions

How do I power the SIM808 module and what is the recommended supply?

The SIM808 module requires a regulated DC power supply between 5V and 18V, capable of delivering peak currents up to 2A during GSM transmission bursts. For vehicle tracking, connect directly to a 12V battery via a fuse and voltage regulator. For battery-powered projects, use a 3.7V LiPo with a boost converter to 5V. Ensure clean, stable power with adequate decoupling capacitors near the module's VBAT pins to prevent voltage drops during RF activity.

What AT commands are used to activate GPS and retrieve location data?

First, ensure the module is registered on the GSM network with AT+CREG?. To enable the GPS receiver, send AT+CGPSPWR=1. Wait for a fix using AT+CGPSSTATUS? until it returns '3D Fix'. Retrieve raw NMEA sentences with AT+CGPSOUT=32 or parsed latitude/longitude using AT+CGPSINF. For autonomous tracking, configure the module to periodically output NMEA data via UART. Always allow several minutes for a cold start fix, or use AT+CGPSRST for a hot start if recent ephemeris data is cached.

Can I use this module with an Arduino or ESP32 development board?

Yes, the SIM808 interfaces primarily via a 3.3V logic-level UART. Connect the module's TXD/RXD pins to your microcontroller's serial RX/TX pins, using a logic level converter if your MCU is 5V. Use SoftwareSerial on Arduino Uno or HardwareSerial on ESP32. Send AT commands to configure GPRS (AT+CGATT=1, AT+CSTT) and establish a TCP connection (AT+CIPSTART). For GPS, parse NMEA strings with libraries like TinyGPS++. Provide a separate 5-12V power source for the SIM808, as the MCU's 5V pin may not supply sufficient current.
