Detailed Product Description:

The SIM800L GPRS Module is a compact and efficient GSM/GPRS board designed for embedded wireless communication. Powered by the SIMCom SIM800L chip, this module supports quad-band (850/900/1800/1900 MHz) frequencies, allowing it to operate globally with any GSM carrier.

It communicates with microcontrollers via TTL serial interface (UART) and supports standard AT commands for SMS messaging, phone calls, and GPRS (internet) connectivity. The module is equipped with a high-gain SMD ceramic antenna or external helical antenna, ensuring reliable wireless communication in compact projects.

Perfect for remote monitoring, GPS tracking, smart irrigation, home automation, and other IoT-based systems.

Empower your IoT and embedded projects with the compact yet powerful SIM800L GSM module, a miniature cellular modem that brings global communication capabilities to your fingertips. This quad-band GSM module supports 850/900/1800/1900MHz frequencies, ensuring connectivity on almost any GSM network worldwide, making it an ideal choice for diverse applications in Pune, Maharashtra, India, and beyond. The SIM800L is renowned for its ability to send and receive SMS messages, initiate and receive voice calls (with an external speaker and microphone), and enable GPRS data transmission for internet connectivity (TCP/IP, HTTP).

Designed for ease of integration, the SIM800L GSM module communicates via a UART (serial) interface, controlled using standard AT commands. This makes it incredibly simple to interface with popular microcontrollers like Arduino and Raspberry Pi. While the core SIM800L chip operates within a voltage range of 3.4V to 4.4V, many common breakout boards incorporate voltage regulators, often allowing direct power input from 5V sources (though a robust power supply capable of providing up to 2A peak current during GSM transmission is crucial to prevent brownouts). Its low power GSM module features include a sleep mode consuming less than 2.0mA, making it suitable for battery-powered applications where energy efficiency is paramount.

The module typically comes with a compact helical antenna, or features a U.FL connector for attaching an external 3dBi GSM antenna for improved signal reception, especially in challenging environments. With a micro SIM card slot conveniently located on the board, getting started is straightforward. Whether you're building a remote control system, an asset tracker, or a basic SMS sending module for alerts, the SIM800L offers a cost-effective and reliable solution. For those looking to buy SIM800L at a competitive SIM800L price in India, consider its robust features and widespread community support for your next connected project.
