Product details
The SIM800L GSM Module is a compact quad-band GSM/GPRS communication module that enables embedded systems and microcontrollers to connect to cellular networks. It allows devices to send and receive SMS messages, make voice calls, and transmit data over GPRS, making it ideal for IoT, remote monitoring, automation, and wireless communication projects.
The module communicates with microcontrollers such as Arduino, ESP32, STM32, Raspberry Pi, and other development boards through a UART serial interface using AT commands. With its small size and low power consumption, the SIM800L is widely used in portable and battery-powered applications.
The SIM800L supports quad-band GSM frequencies (850 / 900 / 1800 / 1900 MHz), allowing it to operate on most GSM networks worldwide.
