SIM800A AE GSM GPRS Module With SMA Antenna | RS232 Interface

The SIM800A AE GSM GPRS Module With SMA Antenna is a cellular communication board that connects to GSM (Global System for Mobile) and GPRS (General Packet Radio Service) networks using a standard SIM card. The gsm 800a ae module operates on dual-band GSM 900 and 1800 MHz frequencies, covering the bands used across India. It communicates with a microcontroller over UART (a two-wire serial interface) or RS232, and supports AT commands (short text instructions) to make calls, send SMS, and open GPRS data connections. The SMA antenna connector gives you the option to use different antennas depending on signal strength in your location.

The sim800a ae gsm module includes an important detail many engineers miss — GPRS data runs on a separate channel from voice and SMS, so you can send a text alert and maintain a live GPRS session simultaneously without interference between them. The module requires 9 to 12V DC supply, but the internal logic runs at lower voltages, so do not connect 12V directly to the UART data lines. The honest trade-off is network generation — GSM and GPRS are 2G standards. In areas where 2G has been phased out, the module will not connect at all, so verify 2G availability in  deployment region before ordering.

The sim800a ae gsm with antenna board works with Arduino IDE, PlatformIO, and any serial terminal for AT command testing. Engineers building remote monitoring systems, students learning cellular IoT communication, and makers building SMS alert devices all use it regularly. To get started, insert an active SIM card, power up at 9 to 12V, and send the AT command over UART to confirm the module responds. StemVolt offers fast and reliable delivery of this module across India with trusted service support.
