PCF8574 IIC I2C Serial Interface Adapter Module IIC I2C LCD Module

Description

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. Do a search for “Arduino LCD PCF8574“. The I2C address is 0x3F by default, but this can be changed via 3 solder jumpers provided on the board. This allows up to 3 LCD displays to be controlled via a single I2C bus (giving each one it’s own address).

Specifications:
5V power supply.
Serial I2C control of LCD display using PCF8574.
The backlight can be enabled or disabled via a jumper on the board.
