Powering

The RGB Matrix will need to be powered by a 5V 4A wall adapter. 5V USB cable is not enough to fully power the display – Glitches and artifacts are displayed when RGB matrix is only powered by USB cable.

Need a lot of 5V power? This switching supply gives a clean regulated 5V output at up to 4 Amps (4000mA). 110 or 240 input, so it works in any country. The plugs are "US...
