As you can see it won't light up correctly, why is it so? Is it possible that there are some issues with common cathode or anode?

I tried using just that smaller one by itself, in a similar fashion to the way I set the big one up.

Led matrixes/matrices

    Schematic (or at least clear photos) of wiring? Code you're using? We're not magicians here; we can't guess as to what's wrong without at least a minimal amount of background on the situation. – stevieb Mar 1 '19 at 20:03
  • You've got it connected backwards. Turn through 180° – Dougie Jul 24 at 23:17

You've got the LED matrix upside down on the circuit board. Turn it through 180°
