Devantech LCD03 20x4 Liquid Crystal Display Module

The LCD03 20x4 LCD Module makes it easy to add an alphanumeric display module to your design. The module includes an integrated display driver which can operate in either I2C or Serial mode. It requires only a 5V power supply and two data connections for either mode, freeing up pins on your processor. Many useful text formatting functions are provided, including the ability to create custom characters. There is a 64 byte FIFO buffer to ensure a minimum of delay in writing to the display.

A backlight is also included, which may be switched on and off under software control.

An I2C interface is available on many popular microcontrollers such as the BASIC Stamp BS2P and may be easily implemented on most PIC microcontrollers using either the PicBasic or PicBasic Pro compiler.
