    I use it with an arduino. I program the arduino with mblock and there is a plugin to use MAX7219 easyly. You just have to choose the led you want to power by sekecting row and column. Great for kids learning to program.

    I ordered two of these displays together upon arriving one worked as intended but the MAX7219 chip on the second display was seated incorrectly and will require re-soldering manually to work as intended. See chip on the left in the image.

    little bit of a pain to program, but it works well and I have had no problems with it so far.
