Description

This is IIC/I2C Serial Interface Adapter Module.
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 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)
