IIC/I2C Interface Adapter Module is used for 16×2 LCD Display. It uses the PCF8574T IC chip which converts I2C serial data to parallel data for the LCD display. Also this interface module simplifies connecting an Arduino to a 16×2 Liquid Crystal display using only 4 wires.
Features

First of all, I appreciate the nice packing. The product served its purpose. But there is no response IF we ring up the number given by you is not at all responsive. which puts us in tension.
