SIM800A GSM GPRS Module with RS232 Interface and SMA Antenna PPTC fuse Gold for these 430K resistorsThe SIM800A Quad Band GSM GPRS Module with RS232 Interface is a complete Quad band GSM GPRS solution in an LGA(Land grid array) . It can transmit voice, SMS, and data with minimal power consumption and supports the 850 900 1800 1900 MHz bands. Using the USB to Serial connector or the RS232 to TTL converter, the RS232 interface makes it simple to connect to a computer or laptop, or to a microcontroller. AT instructions are used to communicate with the
