Description:

This is an I2C Module that can be connected to a standard 162 or 204 Character Display Module that supports 4-bit mode. All Character Modules sold on our site support 4-bit mode, and nearly all commercially available 162 and 204 line character modules support it too.

The I2C Module has aPCF8574 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. Search Arduino LCD PCF8574. The I2C address is 0x3F by default, but this can be changed via 3 solder jumpers provided on the board. The I2C Module allows up to 3 LCDs to be controlled via a single I2C bus (giving each one its address).
