Using Power-over-Ethernet (PoE)

Recently, we had a discussion in Berlin how we can use PoE (Power-over-Ethernet) and weatherproof Ethernet cables for powering e.g. small board with Micro-USB or “Arduino plug”.

I have found some hardware

There is also a Passive PoE Injector Cable Set

@tonke: I heard you also know your way around PoE pretty good. Do you have any thoughts about this you could share with us? Thanks in advance!


There are 802.3at(“PoE+”)-Splitters (&Injektors) (25.4W) available, too. E.g. Delock 87657

And there is, for the Raspberry 3 B+, a PoE-Hat, neatly fitting on the board including a fan, (already) available. (edit: less wires/plugs/connectors ftw)

This lovely piece seems to fit well here:

Seems that the PoE-Hat has some serious problems:
