SIM800A LM317 with Antenna(GSM Finger)- ADIY The SIM800A Quad-Band GSM/GPRS Module with RS232 Interface is a comprehensive solution for Quad-band GSM/GPRS communication. It comes in an LGA (Land grid array) form factor and offers low power consumption while enabling voice, SMS, and data transmission. This module supports the 850/900/1800/1900 MHz bands. To establish a connection with a computer, laptop, or microcontroller, the GSM module features an RS232 interface, which can be utilized through either a USB to Serial connector or an RS232 to TTL converter. Communication with the SIM800A module is achieved using AT instructions. The module comes with a SIM cardholder and an SMA antenna connector. The SIM800A modem consists of a SIM800A GSM chip and an RS232 interface, facilitating easy connections to PCs or laptops via USB to Serial or to microcontrollers using the RS232 to TTL converter. Once the SIM800A modem is connected to the USB to RS232 connector, the correct COM port should be selected by checking the Device Manager of the USB to Serial Adapter. Next, a serial connection needs to be established between the computer and the microcontroller by using a terminal program such as Putty. The connection should be made to the designated COM port at a baud rate of 9600, which is the default baud rate for the modem. Once the serial connection is established, AT commands can be transmitted. For example, sending the command "ATr" should elicit a response of "OK" or another relevant response from the SIM800A modem, depending on the provided command. check out : Sim800 GSM-GPRS-Bluetooth Modem Pinout: Pinout Of SIM800A LM317 with Antenna Features: Quad Band GSM/GPRS modem Supports LTE-FDD, LTE-TDD, and GSM frequency bands Dual frequency of 900/1800 MHz Operating temperature range: -40°C to +85°C Can be connected to a computer or microcontroller Connection options: USB to Serial connector or RS232 to TTL converter Applications: Parking Meter and Taxi Meter For Detection of Navigation
