The part where I want wired ethernet to that SBC, not some funky proprietary wireless chip as in ESP32. I almost found a solution, but I've been unable to get my picoprobe to properly flash and reset the board for some reason, so I haven't been able to use it for development. I'll have to troubleshoot that again sometime if I enter another bout of caring.

In that case the path of least resistance becomes something like a $22 NanoPi NEO (has onboard ethernet, widely used in PiKVM setups)
