Hi
Newbie here.
Can a LAN8720 module be connected to ESP32-C5 devkit? Chatgpt tells me that it cannot be connected directly because the C5 does not have an RMII built into it like the previous versions of the esp32.

Please clarify.
Thanks

Hi,

The ESP32-C5 has no Ethernet, as the ESP32 does, so you can't use the PHY on it as you do on the ESP32.
Only the ESP32 and the ESP32-P4 have Ethernet capability with an external PHY.

The alternative is to use an SPI Ethernet IC.
