Hello, I'm new to using microcontrollers and electronics in general, and I couldn't find the answer to this online. I wanted to know what the purpose of two 5V and GND pins are on this LED matrix, and which pins I need to connect the power to: RGB full-color LED matrix panel, 2mm Pitch, 6…

Why does this LED matrix have two 5V and GND pins?

Power supply 5V / 3A (VH4 header input)

Probably because one pin can't handle 3A.
