Just came across this bit of hardware, which is at a very good price. $50usd.
Lots of gpio, poe. But is it’s s3 and ethernetnet is w 5500 ethernet 
I’m sure there someone out there smarter then me who can make it, and when you do let me know!
Well, you are I luck! The MM version has a fork of WLED that uses ETH-PHY for these boards. However, it does NOT take advantage of the ws500 chip to offload the various network stack to the w500 chip.

I have the Waveshare esp32-s3-ETH POE (I believe it’s the same dev board the fully built out one you shared. So I, along with some help from Co-pilot wrote a firmware to leverage the ws500 chip with WLED.
However, there are a few caveats in using the ws500 chip. The asyncwebserver library won’t bind to the ws500. What this means is you have to use the WiFi for configuring via we UI. The ethernet will only do the pixel control (see more detailed notes on my GitHub Readme.

Sorry, make what exactly? something that properly uses an ethernet PHY rather than an SPI ethernet chip? Something with 8 GPIO? Something else?
As johnvoipguy said, a version of the software that works with that hardware configuration,
Ah i was thinking from the other perspective sorry, I thought you meant changes to the hardware that would give you the functionality you’d need. My bad!
