Fun looking little board. Great to see people sharing these things!
It makes me wonder if there’s interest in more of these type ofESP* dev kit boards. One I haven’t seen is one with just Ethernet PHY but no Ethernet jack/magnetics. It’s been useful in my designs to have a ETH+/- that can be brought out to various Ethernet / PoE setups. Something like the wESP32 is handy for kits but not for integration.
Cnohlr did just this, although he strongly suggests using proper interfacing, but having the bare signal wires at hand can be useful for chip to chip communications on the same board. One could build a board with N ESP chips then connect them directly by daisy chaining their TX and RX pins, that is, passing packets in circle, or behind an Ethernet switch chip, de facto creating a board level local network. Might be interesting for some applications.
