Description

This IIC I2C Interface Adapter for 16×2/16×4/20×14 Characters LCD is an I2C Serial LCD Daughter board that can be connected to a standard 16×2, 16×4, and 20×4 Character Display Module that supports 4-bit mode. All Character Modules sold on our site support 4-bit mode and nearly all commercially available 16×2, 16×4 and 20×4-line character modules support it too. This board has a PCF8574 I2C chip that converts I2C serial data to parallel data for the LCD display. There are many examples on the internet for using this board with Arduino.
