    Description

    Looking for easy to control LED matrix? This 4 in 1 Dot Matrix Display module should be for you. The whole module comes in four 8x8 RED common cathode dot matrix that equiped with MAX7219 IC each. Great to display running text and picture. It can be cascaded to bigger dot maxtrix display, but do make sure the current of 5V is sufficient to support it.

    Note: MAX7219 is operating at 5VDC, it can still interface with Raspberry Pi SPI pin (3.3V), you might need a proper level shifter. And we DO NOT recommend sharing the 5V from Raspberry Pi GPIO pin. Anyway, it can still work with Raspberry Pi :)

    Note: In case you are having hard time to utilize the Arduino example library (the text is reserve or upside down), please check do this in the example sketch:

    Replace
    #define HARDWARE_TYPE MD_MAX72XX::PAROLA_HW
    to
    #define HARDWARE_TYPE MD_MAX72XX::FC16_HW

    or

    #define HARDWARE_TYPE MD_MAX72XX::ICSTATION_HW
