SIM800A Quad Band GSM GPRS Module with RS232 Interface and SMA Antenna

SIM800A Quad-Band GSM GPRS Module with RS232 Interface and SMA Antenna while enables easy connection with the computer or laptop using the USB to 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 Manger 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.
