Re: Neopixels & regulators
We used separate power supplies for the Display processing and LED displays. 2A for the processor and separate 9 amp supplies for the display. Any high demand by the display doesn't brownout the processor that way.
You can search on 3574 here if you want more design info on some over the top LED usage. The 2014 and 2015 robots where both fairly unique.
