More Details:

The I2C and serial display driver provides easy operation of a standard 20*4 LCD Text display. It requires only a 5v power supply and the two data connections for either mode, freeing up pins on your processor. Many useful text formatting functions are provided and also the ability to put together custom characters into memory which can be called off as required. There is a 64 byte FIFO buffer to ensure a minimum of delay in writing to the display. The LCD03 is the same as the LCD02 apart from the added ability to control the backlight in software. It is now easily possible to turn the backlight on and off by sending commands via the I2C / Serial link.

The back of the LCD Board

The four-pin connector is for power and an I2C or serial connection. The seven-pin connector provides a convenient interface for a 3x4 keypad.
