PoE module plugin #6

Open andygrillo opened 4 years ago

Would be good to have the option to add a PoE module that could be plugged in. This would allow for installation in commercial environments with only an ethernet cable connecting the sensor.

I know its been discontinued, but as an example this seemed to work well : https://github.com/particle-iot/ethernet-wing

I never played with PoE, so I was unfamiliar with it. But I've been doing some research and learning about it so I might be able to implement it in the near future, for now though I think i detected our first problem with it, our current Ethernet connector is not made with PoE in mind so I think it's not possible to do it with it, we need to look for an alternative.

Good find. Our ethernet circuit is based on an Olimex ESP32 board. I believe they also have a PoE version so I'll see what components they use there.

Olimex does have some very good reference material, i think this is a good guideline: ESP32-POE-ISO

Oh very nice :) They have kicad files also https://github.com/OLIMEX/ESP32-POE-ISO/tree/master/HARDWARE/ESP32-PoE-ISO-Rev.D
