SIM900A GSM GPRS Module with RS232 Interface and SMA Antenna

SIM900A Modem is built with Dual Band GSM-based SIM900A modem from SIMCOM. It works on frequencies 900/ 1800 MHz. SIM900A can search these two bands automatically. The frequency bands can also be set by AT Commands. The baud rate is configurable from 1200-115200 through AT command. The GSM Modem is having an internal TCP/IP stack to enable you to connect with the internet SIM900A is an ultra-compact wireless module. The Modem is coming interface, which allows you to connect PC as well as a microcontroller with RS232 Chip(MAX232). It is suitable for SMS, Voice as well as DATA transfer applications in the M2M interface. The onboard Regulated Power supply allows you to connect a wide range of unregulated power supplies. Using this modem, you can make audio calls, SMS, Read SMS, attend the incoming calls and etc. through simple AT commands. This is a complete GSM module in an SMT type and made with a very powerful single-chip, allowing you to benefit from small dimensions. SIM 900A GSM Modem with serial and TTL outputs.
