Description
This is 8x8 (row by column 64x LED) dot matrix LED displays module based on MAX7219 IC. The displays are designed so that they can be mounted in a horizontal chain and can also be expanded in a vertical plane allowing versatile displays panel to be built. A convenient 3- wire serial interface connects to all common controller board like Arduino or Raspberry. Individual dot may be addressed and updated without rewriting the entire display. This module can be daisy chain to form a display panel for scrolling message board.
