I have 50 (out of a planned total of 80) 60-led strings of Adafruit Neopixels wired together, each one individually powered and grounded. Everything lights up fine until I get to string #48, which suddenly stops, the first pixel flickering weakly green. it appears to be drawing no current. my power supply’s input is 5V-60A, with three lines going out into six different bus blocks (three for power, three for ground), with about 25 strings attached to each bus block
I am certain that the string in question works (I’ve tested it). I also switched out the string leading into it and confirmed that one for working as well. I am certain that all my connections are solid and that my code is fine. Is there some really stupid obvious reason for this? Do I just need a beefier power supply?
