This is the IIC/I2C Serial Interface Adapter Module.

This I2C Module has an inbuilt PCF8574 I2C chip that converts I2C serial data to parallel data for the LCD.

This is a RoHS-compliant I2C Serial LCD Daughter board that can be connected to a standard 16×2 or 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 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. There are many examples on the internet for using this board with Arduino.

The module has a contrast adjustment pot on the underside of the display. This may require adjusting the screen to display text correctly.
