Hi,
I am working on ESP32 chip and as i know that it supports Ethernet Interface. Now, We have one requirement to use Power Over Ethernet (POE) interface.
So, does anyone has idea about ESP32 will give support of POE in future or any plan for that?
Please let me know if anyone has any idea for that POE interface support into ESP32.
ESP32 support Power Over Ethernet (POE) or not

Re: ESP32 support Power Over Ethernet (POE) or not
POE is mostly based on hardware external to chipset. You have to design it into your PCB or use an external converter. You can do passive POE or hardware POE detection without any involvement of ESP32.
Active POE optionally use some software L2 handshakes, so you asking about SDK functions for this?

Re: ESP32 support Power Over Ethernet (POE) or not
The software handshakes mentioned by WiFive are not supported by our current driver.
The driver is open source though (will be in master any day now), so implementing this feature shouldn't be difficult.

Hi,
Thanks for quick reply.
I just want to know that is it possible to use POE switch with ESP32 which can power up ESP32 and operate it over Ethernet interface.
If possible then provide me some suggestions from hardware and software side if anyone has did before with ESP32.

Maybe this could help :
Also, some DC-DC chips are specially designed for that, such Linear LTC4267 :

Hi,
Thanks for Reply.
But, is ESP32 capable to operate it on POE switch after designing circuitry of POE with ESP32? Let me know if you have some more idea regarding stability and functionality of POE with respect to ESP32 chip.

Re: ESP32 support Power Over Ethernet (POE) or not
POE is a standard that can deliver about 36W of power. I'd say that's more than enough to drive an ESP32, so as long as you have a design that does its job well, there's absolutely no problem driving an ESP32 from PoE. We will eventually be releasing a devboard with Ethernet on it; we are aiming to also have PoE included and will release the schematics when it is done.

Please let me know once Espressif System release ESP32 Development with Ethernet support and POE support as well.
