I have 8 8x8 WS2812 Matrix LED boards connected together to make 2 16x16 matrices. I have them connected with Dupont wires.
I also power the 2 16x16 with Dupont wires that are connected to a 5v 60Amp PSU (More Leds will be added later). The PSU power should easily support the LED power requirements however, if I set the brightness anything over 30...the first matrices start to get reddish at the end. They start white but as the end they are orange/red. If I set the brightness to 20-25 they are white. So there must be something with the power but I have 60amps...Can it be that the Dupont cables are the bottleneck? The cables don't get hot...so I guess they are ok?
Any help is highly appreciated.
