SIM800C Quad-Band GSM/GPRS Modem Module w/ Antenna & RS232
The SIM800C Quad-Band GSM/GPRS Modem integrates the SIM800C engine with an onboard RS232 interface and SMA antenna for reliable M2M communication. It operates on 850/900/1800/1900MHz bands and is controlled via AT commands, making it ideal for Arduino, Raspberry Pi, and industrial PLC integration.
Features
- Quad-band GSM/GPRS engine (850/900/1800/1900MHz) for global cellular connectivity.
- Integrated RS232 DB9 female connector with MAX3232 level shifter for direct PC or MCU interfacing.
- Onboard regulated power supply accepts 5-12V DC input via RMC connector or DC jack.
- Includes detachable SMA antenna and features a slide-in SIM card tray for easy setup.
- Built-in TCP/IP stack enables direct GPRS internet, SMS, and voice call functionality via AT commands.

The GSM SIM800C Modem is a robust cellular communication module built around the industrial-grade SIM800C chipset from SIMCom. It provides a complete RS232 interface solution with an onboard MAX3232 transceiver, allowing direct connection to computers, microcontrollers, or RS232-compatible industrial equipment without additional hardware. The module’s wide input voltage range (5-12V DC) is managed by a high-current LDO regulator capable of handling the surge currents required during GSM transmission bursts.
Engineered for continuous operation in harsh environments, the modem supports the full suite of GSM phase 2/2+ features, including GPRS multi-slot class 12/10 for data transfer. Its configurable baud rate (9600-115200) and comprehensive AT command set (3GPP TS 27.007/27.005 and SIMCom enhanced) offer precise control for SMS, voice calls, and TCP/IP data sessions. The inclusion of an SMA connector with a stub antenna ensures immediate RF deployment, while the FR4-grade PCB guarantees long-term reliability for embedded IoT and M2M systems.
