Description

The GA6-B Mini GPRS/GSM Module is a compact development board centered on the SIM800L transceiver, designed for embedding cellular connectivity into IoT and M2M systems. It provides robust 2G network support for SMS messaging, voice call functionality, and packet-switched GPRS data services, enabling remote telemetry, alert notifications, and basic internet connectivity in areas without Wi-Fi.

Engineered for developer integration, the board exposes dual UART serial interfaces—one for AT command communication with a host microcontroller (e.g., ESP32, Arduino) and another for firmware updates. It supports a wide operating temperature range from -30°C to +80°C and features certified compliance (ROHS, FCC, CE, CTA), making it suitable for industrial deployments, asset tracking devices, and smart agriculture sensors.

Key Features

  • Full-featured GSM/GPRS module based on the SIM800L chipset for global 2G network compatibility.
  • Enables SMS text messaging and voice call capabilities for alerting and remote communication systems.
  • Provides GPRS data connectivity with maximum rates of 85.6 Kbps download and 42.8 Kbps upload.
  • Supports standard GSM07.07 and GSM07.05 AT command sets plus extended AI-Thinker proprietary commands.
  • Dual serial port design: one port for AT command interface and a separate port for firmware download and debugging.
  • Integrated audio codec supports digital and analog audio with HR, FR, EFR, and AMR voice coding.
  • Low standby current consumption (below 3mA) enhances battery life in portable and solar-powered applications.
  • Certified for ROHS, FCC, CE, and CTA standards, ensuring regulatory compliance for commercial products.

Applications

  • Remote environmental monitoring and telemetry systems sending sensor data via SMS or GPRS.
  • GPS asset tracking devices for fleet management, sending location updates over cellular networks.
  • Smart agriculture sensors for soil moisture or temperature alerts directly to a farmer's phone.
  • Industrial IoT (IIoT) alarm systems and machine condition monitoring with automated voice call alerts.
  • Battery-powered security systems and personal safety devices requiring low standby current.

Frequently Asked Questions

What is the correct power supply voltage for the GA6-B SIM800L module?

The SIM800L chip requires a stable 3.4V to 4.4V DC power supply, typically 3.7V from a Li-Po battery or a regulated 4V source. Ensure the power supply can deliver peak currents of up to 2A during transmission bursts to prevent voltage drops and module resets. Incorrect voltage can damage the RF power amplifier.

How do I communicate with this GSM module using a microcontroller like Arduino?

Connect the module's TX and RX pins (AT command UART) to your microcontroller's serial pins. Use a logic level converter if your MCU is 5V. Initialize serial communication at 9600 or 115200 baud. Send standard AT commands (e.g., AT+CMGS for SMS) and parse the responses. Always include a delay after power-on for the module to register on the network.

Can I use this module for GPRS internet connectivity and HTTP requests?

Yes, after inserting a valid 2G SIM card, use AT commands to attach to the GPRS network (AT+CGATT=1), configure the APN (AT+CSTT), and activate the context (AT+CIICR). Then, you can open TCP connections (AT+CIPSTART) and send HTTP data. Maximum GPRS speeds are 85.6 Kbps download, suitable for sending sensor data or small JSON packets to a cloud server.

What is the typical standby current, and how can I reduce power consumption?

The module's average standby current is below 3mA when registered on the network. To minimize consumption, utilize the AT+CSCLK command to enable slow-clock mode during idle periods or use AT+CFUN to put the module into minimum functionality sleep mode. For ultra-low power designs, cycle power completely and wake only for scheduled transmissions.
