Serial I2C LCD Daughter Board Module

This is I2C Serial LCD Daughter board that can be connected to a standard HD44780 compatible 16x2, 20x4, or 20x2 Character Display Module that supports 4-bit mode. All Character Modules sold on our site support 4-bit mode, and nearly all commercially available 16x2 and 20x4 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 internet for using this board with Arduino. 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).
