The LCD03 is a 20 x 4 character display that is easy to hook up to any microcontroller thanks to its support for both serial and I2C interfaces requiring only 2 data pins on the controller, plus power & ground.
Control of the backlight can be done through software via the I2C or serial interface. A 100 byte FIFO buffer is included to speed up writing to the display to avoid blocking the controller and there is support for formatting custom characters that can be stored in memory and written to screen.
A 3x4 keypad can also be connected directly to the LCD display which will scan the keypad and provide data for reading via the I2C or serial interface.
