Ethernet rj45 support on ESP32?

Question

Arduino

I'm going to switch from arduino uno + ethernet shield w5100 to esp32 board. According to my tasks, WiFi is not suitable and cable support is needed. I didn’t find any ready-made solutions for implementing RJ 45 on esp32 by googling ...
How can I solve such a problem?

Answer 1

For some reason, esp32 phy does not have an interface, you need to fence the attached chip. Well, write the Lwip driver for this chip in esp32.

is on Ali, but the price tag is biting.
It will be cheaper to spin a cheap RMII thread on the LAN8720 for example to the dev kit.

Answer 3

Maybe this option will work for you
