Clock Fascia Matrix:
In the illustration above, each of the similarly colored 4×4 character groups will be lit up by the 4×4 Led matrix board. So in all the clock will use 8 such boards to give a 16×8 matrix. Each 8×8 cluster i.e 4x4x4 will be controlled by an MAX7219 breakout board. MAX7219 can control 64 LEDs and thus can control a 8×8 LED matrix. The thin green line in the illustration above is indicative of the demarcation of MAX7219 limits. Hover it is apparent that at the centre some words (highlighted in yellow below) are spread over two 4×4 panels and they need to be handled specially.
