SIM 800C GSM Modem with SMA Antenna

SIM 800C GSM Modem with SMA Antenna

This is SIM 800C GSM Modem with SMA Antenna, The baud rate range of the GSM Module can be easily configured using AT commands, allowing you to set it anywhere between 9600 and 115200. This versatile GSM GPRS Modem incorporates an internal TCP/IP stack, enabling seamless internet connectivity through GPRS. Its capabilities make it a perfect choice for M2M interface applications that involve SMS, voice, and data transfer.

One of the standout features of this modem is its onboard regulated power supply, which offers compatibility with a wide range of unregulated power sources. This means you can connect the modem to various power inputs without any hassle. With this modem at your disposal, you can effortlessly perform numerous tasks such as making audio calls, sending and receiving SMS, reading SMS, and accessing the internet using simple AT commands.

The modem utilizes the highly reliable Quad-Band GSM/GPRS engine SIM800C, manufactured by SIMCOM, which operates on frequencies ranging from 850 MHz to 1900 MHz. To establish a direct connection with a computer or any other RS232 compatible devices, the modem features a convenient DB9 female connector. The necessary RS232 level conversion is seamlessly achieved through the use of the reliable MAX3232 module from MAXIM Semiconductor.

To power the modem, a 5-12V DC power supply is required, and you have the option to provide it either through the onboard 2-pin RMC connector or the DC jack. To effectively handle situations where high surge currents (up to 2A) may be encountered, the modem is equipped with a robust high current low dropout linear voltage regulator.
