I've been running some more tests and I think the issue with the neopixels is simply voltage. I swapped the new IO board over to pairs of 24 gauge shielded speaker wire and the neopixels are doing the same thing. Testing the voltage at the first neopixel I can see it's at 3.3V when it should be near 5v. The only other power wires I have are 18 gauge so I'm going to swap just the power wire out for that to see if I can decrease the voltage drop and stabilize things. That's my next test. If that doesn't resolve it then I may need to send the 11.1v to the wand and use a buck converter to drop it back down to 5v. I've got a ton of those buck converters and can just stick it inline. I know that's brute forcing a solution but I don't have much more time to futz with this.
