Sim 800C GSM Module

GSM/GPRS Communication: Like other SIM800 series modules, the SIM800C provides 2G GSM/GPRS connectivity, enabling devices to communicate over cellular networks. It supports various frequency bands depending on the region.

SIM Card Slot: The module typically includes a standard-sized SIM card slot where you can insert a SIM card from a mobile network operator. This SIM card provides the necessary credentials for network access.

Serial Communication: SIM800C communicates with a microcontroller or other devices using UART (Universal Asynchronous Receiver-Transmitter) serial communication. You send AT commands to the module to control its functions and receive responses.

AT Commands: Interaction with the module is typically done through AT commands. These commands are sent to the module to perform actions such as making calls, sending SMS, connecting to the network, and more.

Voice Support: SIM800C is capable of handling voice functionality, including making and receiving voice calls. It can also transmit and receive voice data, making it suitable for voice communication applications.

External Antenna: To ensure strong signal reception, the module often requires an external GSM antenna. It features a connector for attaching an external antenna.

Power Supply: SIM800C typically operates on a supply voltage in the range of 3.4V to 4.4V. It also supports low-power modes to conserve energy when not actively transmitting or receiving data.

GPIO Pins: Some versions of the SIM800C module come with General Purpose Input/Output (GPIO) pins, allowing you to interface with other devices or sensors.

TCP/IP Stack: Certain variants of SIM800C may include an integrated TCP/IP stack, enabling it to connect to the internet via GPRS. This feature is valuable for IoT applications.

Compact Form Factor: The module is usually available in a compact form factor, making it suitable for embedding into various devices and projects.

LED Indicators: Some modules feature LED indicators to display the module's status, such as network registration, data transmission, and more.

SMS and Data Transfer: SIM800C can send and receive SMS messages and transfer data over GPRS. This functionality is valuable for remote monitoring and control applications.
