This modem is built with SIM800A that supports Quad-band 850/900/1800/1900MHz, it can transmit Voice, SMS and data information with low power consumption. With a small footprint, it can fit into slim and compact demands of customer design and is especially useful for faster turnaround time in development phase as well as manufacturing of larger systems.

The Modem comes with TTL interface, which allows the user to connect to microcontroller as well as PC through USB to TTL module. The baud rate is configurable from 9600- 115200 through AT command. The GSM/GPRS Modem is having internal TCP/IP stack to enable the enable the user to connect with internet via GPRS. It is suitable for sending SMS, Voice as well as DATA transfer application in M2M interface. Using this modem, user can make audio calls, sending SMS, Reading SMS, attend the incoming calls and internet etc., through simple AT commands.
