cnlohr managed to add Ethernet to a esp8266 module (1) using the i2s signals also present in the esp32-c3 and a driver plus magnetics. Once the transformer is in place, passive PoE can be added with a regulator connected to the relevant transformer pins, probably 2 and 7 in the schematic at (2), but yeah, the size grows significantly. 1- https://github.com/cnlohr/espthernet https://github.com/cnlohr/espthernet 2- https://github.com/cnlohr/espthernet/blob/gh-pages/hardware/esp12e-ethernet.pdf https://github.com/cnlohr/espthernet/blob/gh-pages/hardware/...
