GSM/GPRS TTL UART MODEM-SIM900A

Description : rhydoLABZ’s  GSM/GPRS TTL UART Modem is built with Dual Band GSM/GPRS engine- SIM900, works on frequencies  900/ 1800 MHz. The Modem is coming with selectable interfacing voltage,which allows you to connect 5V & 3V3 microcontroller directly without any level conversion chips. 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.

Note:Please note that Sim900A is a dual-band module suitable only for Asian countries. For world wide usage please choose GSM/GPRS modems embedded with Sim900 module.

The Modem is manufactured with Automatic Pick and place machine with high quality standard.The onboard Low dropout 3A Power supply allows you to connect wide range unregulated power supply (5V-12V)  . Using this modem,you can make audio calls, SMS, Read SMS, attend the incoming calls and internet ect through simple AT commands.
