The SIM800L GPRS GSM module for Arduino is a compact and versatile device that operates on GSM850MHz, EGSM900MHz, DCS1800MHz and PCS1900MHz frequencies, allowing it to connect to GSM networks worldwide using a 2G SIM card.

This module is ideal for projects that require mobile communication, as it allows you to make and receive voice calls, send and receive SMS messages, as well as transmit data via GPRS (TCP/IP, HTTP, among others). It also includes an integrated FM receiver and support for standard AT commands, making integration and control easier.

Main features:

Operating voltage: 3.4V to 4.4V, with low power consumption in sleep mode (0.7 mA).
UART Serial interface for communication with microcontrollers such as Arduino.
Quad-band compatibility (850/900/1800/1900 MHz) for global coverage.
Ability to make voice calls using a headset or external 8Ω speaker and electret microphone.
Sending and receiving SMS.
GPRS data transmission with maximum speed of 85.6 Kbps and TCP/IP protocol integrated into the chip.
Support for AT commands (3GPP TS 27.007, 27.005 and SIMCOM enhanced AT Commands) with automatic baud rate detection.
Support for A-GPS, USSD and real-time clock (RTC).
uFL connector for external antenna, improving signal reception.

This module uses the same SIM800L chip as the Adafruit FONA module, so it is compatible with the same libraries, making it easier to program and use in Arduino projects.

Typical uses:

IoT projects that require mobile communication.
Tracking and location devices with A-GPS support.
Alarm systems and remote monitoring.
Automation and remote control via SMS or GPRS data.

Compatibility: Compatible with Arduino boards and microcontrollers that support UART communication. Requires a stable power supply between 3.4V and 4.4V for optimal operation.

Quad-band GSM/GPRS device for global coverage.
Compatible with Arduino via UART Serial interface.
Enables voice calls, SMS sending and receiving.
GPRS data transmission up to 85.6 Kbps with TCP/IP protocol.
Low power consumption in sleep mode: 0.7 mA.
Supports standard AT commands and Adafruit libraries.
Includes a uFL connector for an external antenna.
Support for A-GPS, USSD and real-time clock (RTC).

Customer Questions & Answers

How is the SIM800L connected to a microcontroller such as Arduino, and what should be considered for UART communication?

Communication between the SIM800L and Arduino is via UART interface (TX-RX and RX-TX). It is vital to level-shift the voltages, as the SIM800L uses 2.8 V logic and a typical Arduino operates at 5 V; a resistor divider is recommended for the module’s RX pin. Supported baud rates: 1200–115200 bps (default: 9600 bps).

What features does the included antenna have, and what type of connector is used for replacement?

The module includes a uFL connector for the GSM antenna. A PCB or wire-type antenna is generally supplied, although this may vary depending on the supplier. For better reception or use in metal enclosures, an external antenna compatible with a uFL connector or uFL-SMA adapters can be used.

What data protocols does the module support, and what are the maximum GPRS transfer speeds?

The SIM800L supports integrated TCP/IP protocols and HTTP via AT commands. The maximum GPRS data speed is 85.6 kbps (downlink/uplink). It uses CS-1 to CS-4 coding. It is important to note that GPRS performance may be limited by network quality and congestion.

Is the SIM800L module compatible with Arduino?

Yes, the SIM800L module is compatible with Arduino and communicates via UART Serial interface, using standard libraries such as Adafruit's.

What voltage does the SIM800L module need to work?

The SIM800L module requires an operating voltage between 3.4V and 4.4V for correct operation.

Can I send and receive SMS messages with this module?

Yes, the SIM800L module allows you to send and receive SMS messages using AT commands.

What GSM networks does the SIM800L module support?

The module supports quad-band GSM networks at 850/900/1800/1900 MHz, compatible with any worldwide GSM 2G network.

Does the SIM800L module include an antenna?

The module includes a uFL connector for an external antenna, but the antenna must be purchased separately if it is not included in the package.
