Description

SIM 800a GSM Module – SIM800A Quad-Band GSM/GPRS Module with RS232 Interface.

The SIM800A Quad-Band GSM/GPRS Module with RS232 Interface is a complete Quad-band GSM/GPRS solution in an LGA(Land grid array) type which can be embedded in the customer applications. SIM800A supports Quad-band 850/900/1800/1900 MHz, it can transmit Voice, SMS, and data information with low power consumption.

With tiny size of 100 x 53 x 15 mm, it can fit into the slim and compact demands of custom design. Featuring an Embedded AT, it allows total cost savings and fast time-to-market for customer applications.

The SIM800A modem has a SIM800A GSM chip and RS232 interface while enabling easy connection with the computer or laptop using the USB to the Serial connector or to the microcontroller using the RS232 to TTL converter. Once you connect the SIM800A modem using the USB to RS232 connector, you need to find the correct COM port from the Device Manager of the USB to Serial Adapter.

Then you can open Putty or any other terminal software and open a connection to that COM port at 9600 baud rate, which is the default baud rate of this modem. Once a serial connection is open through the computer or your microcontroller you can start sending the AT commands. When you send AT commands for example “ATr” you should receive back a reply from the SIM800A modem saying “OK” or other response depending on the command sent.
