MAX7219 LED Dot Matrix

This is Dot Led Matrix Module incorporating MAX7219 Driver chip. By using this dot LED module in your upcoming project, you will be able to add some great cool animation.

The individual module features 32×8 LED’s, each controlled very precisely by the MAX7219 driver to generate the color pattern you wish. The great advantage of using this is users will have control over all of the 256 LED by just connecting 3 output communication wires to microcontrollers like Arduino etc.

Specifications
