IOT GSM 2G Module Board ES-GSM-M3-U


IOT GSM 2G Module Board ES-GSM-M3-U

This module builds with a band of GSM/GPS. It's based on the SIM900A modem and contains the frequencies of 900/1800MHz. This GPRS module circuit has to build with the communication between mobile or other gadgets like computers and laptops. This module work on the base of wireless mode communication with the network of GSM. GSM/GPRS will modulate and demodulate the wireless network's signal and allow it to connect with the internet. The complete GSM module chip will allow you to benefit from the small dimensions.

IOT GSM 2G Module Board ES-GSM-M3-U In Details

This module of the SIM900A modem will allow telephone technology to provide comprehensive data with a wireless network. SIM900A will enable the search automatically for the bands. The command rate sets at between1200-115200. The modem will allow the PC to communicate with a microcontroller equipped with an RS232 chip. Connecting to a wide range of unregulated power suppliers is possible with a regulated onboard power supply.

They will find the RS232 level conversion value using MAX3232 from the semiconductor. It will work with the 5-12V DC and feed through an onboard pin connector or DC. High surge current requirement stands for the High Current Low dropout linear voltage regulator power as included in the modem—the Micro SIM card connector in the base of push in and out. The UART TTL outputs of the modem interface 3.3v/5v. The modem configures receiving and sending data will automatically reach a destination.

Special Features

It contains the power supply 5v 1amp to 2amps maximum.
MIC and Speaker will automatically connect options in the modem for calls.
It consumes the total signal strength around the areas.
Enables RS232 with DB9 connector, TTL pins, and I2C pins for communication.
Modem perfectly matches the GSM-based microcontroller projects.
It consumes the low power and It includes the stub antenna and SMA connector.
