A 5V power supply is also required, not included, for powering the matrix itself. The Pi cannot do it due to the high currents. To calculate the max current of your matrix set up, multiply the width of all the chained matrix by 0.12 : A 32 pixel wide matrix needs 32*0.12 = 3.85A so pick up a 5V 4A power supply. Please note: this HAT is only for use with HUB75 type RGB Matrices. Not for use with NeoPixel, DotStar, or other 'addressable' LEDs.
