-SIM900A Modem is built with Dual Band GSM based totally SIM900A modem from SIMCOM. It works on frequencies 900MHz.
-SIM900A can seek these bands mechanically. The frequency bands can also be set through AT Commands.
-The baud charge is configurable from 1200-115200 via AT command. SIM900A is an extremely compact and wi-fi module.
-The Modem is coming interface, which lets in you join PC in addition to microcontroller with RS232 Chip(MAX232).
-It is suitable for SMS, Voice as well as DATA transfer utility in M2M interface. The onboard Regulated Power supply allows you to connect wide variety unregulated strength supply.
-Using this modem, you could make audio calls, SMS, Read SMS, attend the incoming calls and ect. Via simple AT instructions.
-This is a whole GSM module in a SMT kind and made with a very powerful single-chip, permitting you to advantage from small dimensions.
-SIM 900A GSM Modem with serial and TTL outputs.
