Description:
The SIM800L GPRS GSM Module is a compact and powerful wireless communication module designed for IoT, automation, tracking, and remote monitoring applications. Featuring quad-band GSM/GPRS support (850/900/1800/1900 MHz), it enables devices to send and receive SMS messages, make voice calls, and access mobile data services through GPRS networks. The module uses a Micro SIM card and communicates with microcontrollers such as Arduino,
ESP32, STM32, and Raspberry Pi via a TTL serial (UART) interface, making integration simple and efficient. Its small size, low power consumption, and support for AT commands make it an ideal choice for embedded and battery-powered projects. The SIM800L also supports TCP/IP communication, real-time clock functions, and reliable wireless connectivity for a wide range of GSM-based applications.
