Description

The SIM800A Quad-Band GSM/GPRS Module with RS232 Interface is a complete Quad-band GSM/GPRS solution in an LGA(Land grid array) . It can transmit voice, SMS, and data with minimal power consumption and supports the 850/900/1800/1900 MHz bands.
Using the USB to Serial connector or the RS232 to TTL converter, the RS232 interface makes it simple to connect to a computer or laptop, or to a microcontroller. AT instructions are used to communicate with the SIM800A. A SIM cardholder and an SMA antenna connector are included.

The SIM800A modem has a SIM800A GSM chip and an RS232 interface for easy connection to a PC or laptop via USB to Serial or to a microcontroller through the RS232 to TTL converter. After connecting the SIM800A modem to the USB to the RS232 connector, check the Device Manager of the USB to Serial Adapter and choose the correct COM port.
Then, using Putty or another terminal program, open a connection to that COM port at 9600 baud, which is the modem's default baud rate. Transmitting can begin AT commands once a serial connection has been established between the computer and the microcontroller. While transmitting AT commands, such as "ATr," the SIM800A modem should respond with "OK" or another response depending on the command provided.

Further Info

SIM800A is a Dual-band GSM/GPRS module that works on frequencies EGSM 900MHz and DCS 1800MHz. SIM800A supports GPRS multi-slot class 12/ class 10 (optional) and supports the GPRS coding schemes CS-1, CS-2, CS-3 and CS-4. SIM800A is designed with a power-saving technique so that the current consumption is as low as 0.55mA in sleep mode.

Its small size allows it to fit into the custom design's sleek and compact requirements. Its Embedded AT enables comprehensive cost reductions and a quick time to market for client applications.
