As per "Devil Man" I got mine working

I had tons of trouble getting this to work until I read " Devil Man" review. Now all works great.

MAX7219 = GREAT! Using MD_MAX72XX, display mirrored? Add this to your Sketch!

This MAX7219 is RED, BRIGHT, Great display and easy to use! If you are using the latest MD_MAX7219 {GitHub MajicDesigns/MD_MAX72XX} you may notice, that, your display looks odd (see my image)! Try adding this to your Arduino Sketch: #define HARDWARE_TYPE MD_MAX72XX::ICSTATION_HW Comment or delete any other of the above #defines, ie //#define HARDWARE_TYPE MD_MAX72XX::PAROLA_HW // Arbitrary output pins MD_Parola P = MD_Parola(HARDWARE_TYPE, DATA_PIN, CLK_PIN, CS_PIN, MAX_DEVICES); Marco Colli has made major changes to his code, so, many of the code examples, that, you find on the Internet will not work, correctly! You no longer need to edit the MD_MAX72xx.h file (can't anyway, totally revised). Many of the YouTube videos suggest, that, you edit this file, this no longer possible with the latest update, available at GitHub. I hope, that, this helps!

VERY NICE!

Big Thanks to DEVIL MAN!! Board is nice as well.
