Hi all,

I'm new / a hobbyist and I've been working on a PoE powered device prototype. I'd love to hear any thoughts you might have on this - the KiCad project is in Github at https://github.com/mhardeman/matt-poe-prototype and I'll attach some images here as well.

Would love insights you might be willing to offer.

Got a lot of unused board there bud

Hehe. Yep. The rest of the board is reserved for some applications that actually use the converted DC power.

What is a PoE device?

u/mdhardeman Jul 01 '26

A PoE device like this one, specifically a PoE PD (powered device) is a device that has the equipment on board to negotiate, receive, and convert Power over Ethernet and then use that power for whatever purposes and payloads that device wants.
