Its IEEE802.3af compliant POE. POE Input voltage range 36V to 57V on pins 4,5 & 7,8. Will accept either AC or DC POE.
Has 5v Output from POE to header to power your own things up to 9W.
Will accept external 5V DC in up to 17v, and has a 3.3v output pin providing up to 1A from onboard power supply.
Onboard LAN using LAN8720A.
Here it is powered up via POE. I think its one of the smallest ESP32-POE boards out there (that I have seen anyway)
I also made a even smaller board like this that its the same just not POE.
