Description :

                GSM/GPRS TTL+232 UART Modem is built with Dual Band GSM/GPRS engine- SIM800L , works on frequencies 900/ 1800 MHz The level The baud rate is configurable from 9600-115200 through AT command. The GSM/GPRS Modem is having internal TCP/IP stack to enable you to connect with internet via GPRS. It is suitable for SMS, Voice as well as DATA transfer application in M2M interface.

                The modem comes with selectable interfacing voltage which allows you to connect 5V & 3V3 microcontroller directly without any additional level conversion chips. SIM800C module is having internal TCP/IP stack to enable you to connect with internet via GPRS (supports the GPRS coding schemes CS-1, CS-2, CS-3 and CS-4). The Modem is coming with RS232 interface, which allows you connect PC as well as microcontroller with RS232 Chip(MAX232).
