SIM800C GSM/GPRS Module

GST

The SIM800C GSM GPRS Module is a compact communication module used for SMS, voice calls, and GPRS data in embedded and IoT projects. It works with boards like Arduino Uno R3 and ESP32 Development Board.

The SIM800C is a compact version of the SIM800 series, designed for space-constrained applications. It supports quad-band GSM/GPRS communication, enabling devices to send SMS, make calls, and access mobile data.

Compared to SIM800L, the SIM800C is often used in industrial and embedded designs due to its smaller size and better integration options. It communicates with microcontrollers using UART (serial interface) and is controlled via AT commands.

This module is widely used in IoT devices, GPS trackers, smart metering, remote monitoring, and automation systems.
