Mini SIM800L GSM GPRS Module – Ultra-Compact Quad-Band MicroSIM Card Core Board with TTL Serial Interface for Arduino and IoT Projects
The SIM800L GSM GPRS Module is an ultra-compact and powerful cellular communication module that enables your microcontroller projects to connect to GSM networks for voice, SMS, and GPRS data transmission. Based on the SIM800L chipset, this core board supports quad-band frequencies (850/900/1800/1900MHz), ensuring global GSM compatibility.
Designed with minimal footprint, this is one of the smallest GSM modules available, making it ideal for space-constrained IoT applications, such as remote monitoring, smart tracking, home automation, and wireless data transmission.
It features a MicroSIM card slot, onboard network status LED, and communicates via TTL-level serial interface (UART), allowing seamless integration with Arduino, ESP8266, ESP32, STM32, and other 3.3V logic-level microcontrollers.
