The Blue LED matrix display has been provided to allow easy interface via a MAX7219 LED Driver to a matrix of 64 LEDs. A convenient 4-wire serial interface connects to all common microprocessors. Additionally, multiple LED matrices can be combined to form a larger display from 1-16 matrices. That is a possibility of over 1024 LEDs!
