This large matrix display is essentially a collection of four 8x8 dot matrix modules that are joined together to create an 8x32 dot matrix display. These can work together by using the MAX7219 LED Driver IC module, or can be split apart to work individually in separate projects. The panel of displays operate on 5V, with 16 total mounting holes of 3mm each. It can be interface via serial or SPI, and all of the matrices can be controlled via a single input – with the output of each module connected to the next module’s input.
