SMD GSM Module SIM800C SMT Modem with Antenna

The SIM800C is a powerful quad-band GSM/GPRS module designed for seamless integration into IoT and communication devices. Operating on 850/900/1800/1900MHz frequencies, it enables reliable voice calls, SMS messaging, and data transmission with minimal power consumption. Its compact SMT package (17.6×15.7×2.3mm) makes it ideal for space-constrained applications. The module features 42 pins including analog audio interface, RTC backup, USB, serial ports, GPIO, ADC, and external SIM card support (3V/1.8V). With its built-in TCP/IP stack and configurable baud rate (9600-115200), this module simplifies implementation of cellular connectivity in your projects. Whether you're building remote monitoring systems, GPS trackers, or smart meters, the SIM800C provides a robust communication backbone with global coverage.
