OK, so what is up with POE hats?
OK, so what is up with POE hats?
Why do the vast majority of these seem to either block off the 40pin header or convert it to female header that's incompatible with further hats? And why are they full sized, despite having minimal circuitry on them? I can appreciate the ones that build in a cooling system, but that doesn't need to block off all the pins that aren't being used by the hat.
It seems like all this could be accomplished with a small board that doesn't interfere with everything else one intends to do with a Pi or Pi-clone. In fact, I'm surprised at the lack of built-in POE Pi boards out there.
You're viewing a single thread.
you could litterally achieve this with an inexpensive adapter
edit: it works by plugging a normal ethernet cable, add an 5v power adapter (net, battery, anything really) and at output of adapter you attach an PoE eth cable. An reverse working adapter also exists, if your hardware at the end of the chain needs a 5v input, if needed
So is this an inline plug that has a 5v pigtail? I'd be interested in a link if you've seen one for sale?

They are called PoE injectors
Holy cow I'm definitely converting everything to POE now
That is a power over an ethernet cable, it is not the Power over Ethernet.
If you plug one end of that into your power source, and the other into into some random device unknowingly you're probably gonna blow it up.
Thanks for the link. I've only ever seen the input side of POE injectors as all the devices were set up for receiving POE natively. This looks like it would work.
No problem! I love wired security cams, so I have a bunch of these sets to power camera's. Try to jam that thugs! Just an old raspberry pi + network switch and a bunch of PoE powered cameras. Very cheap, very secure
+1 on wired cams. I put in cameras for neighbors that use them for calving barns or monitoring pens, and I would never use wireless, even though there's no interference sources when you're 2 miles from the nearest neighbor. It's just so much more reliable. That's where I've used POE switches and injectors, but I've never encountered a version that sits inline for pigtailing off the power leads, but I guess I should have predicted that they'd exist.
Cheers!
No problem! I am sure this solution will work for you, especially for the price you cant go wrong! Shoutout to team wired!
