Description:
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 internal TCP/IP stack to enable you to connect with internet SIM900A is an ultra compact wireless module. This is a complete GSM module in a SMT type and crafted with a very powerful single-chip processor integrating AMR926EJ-S core, allowing you to benefit from small dimensions.
