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
Serial I2C control of LCD display using PCF8574
5V power supply
Backlight can be enabled or disabled via a jumper on the board
