After a review of the posts on this thread, I realise what a good deal the UniFi CloudKey is.

 

I'm surprised nobody has mentioned solar cells(yet). One of the server farms I use is solar powered, and it works.


What are you talking?

There's also a card for the RPi3B, as I have such and am powering a non+ via POE.

 

I used this one.

A bit pricey, but it was the only good option at the time, also had to ahve some soldering work done on it so I could also use the GPS hat I put on it.

Re: Raspberry Pi via POE

I really wish someone would make an isolated 802.3at and even an 802.3bt PoE Pi HAT.....

Re: Raspberry Pi via POE

There are different splitters, some with 10/100 Mbps and others with 10/100/1000 Mbps.

Look out for the power rating, not all has 2.5A

 

This one is 2.4A and 10/100/1000 Mbps.

I am using this with Raspberry Pi model 1, 2 and 3 and a UniFi Switch 16 POE-150W.

Re: Raspberry Pi via POE

I doubt anyone will make an AT ot BT POE hat for the pi because.
AF max power 2A
AT max power 5.1A
BT max power 14.2A

https://en.wikipedia.org/wiki/Power_over_Ethernet
Power amounts are the max currents that would be available if the POE max power is converted to 5v.

So with AF already getting 2A and there not being much need for that last .5a for most people.

Though AT might be nice for that extra .5, but I'm not sure they'd bother with the R&D to get that little extra.

The current official HAT is 802.3af... Do you need more than 15.4W on your R-Pi? Recommended PSU capacity for  a 3B+ is 2.5A... That's 12.5W (At 5V). Max peripheral draw for a 3B+ is only 1.2A (6W).

Re: Raspberry Pi via POE

You're both thinking of things to be directly powered by the Pi.....

 

What if for example you wanted to power 80W of addressable LED strip(s)? What if you wanted to power a 10" LCD touch screen directly? Multiple opportunities with more power....

Well...

 

1. The title specifically says Raspberry Pi via POE

2. The previous did specify a HAT for the pi...

 

80W of addressable LED strips also wont' be powered from a Pi... But yeah, you could power from a splitter... If you can find a device that'll supply 80W per POE port of course...

Re: Raspberry Pi via POE

No reason why a PoE HAT for the Pi couldn't supply power to the Pi itself and something else offboard.

 

Either way, for now, the best option is one of the following:

 

1. One of the many options from Adafruit (including the official RPI PoE HAT -

2. One of these -

The latter is NOT isolated though.

Re: Raspberry Pi via POE

@stekkerdoos
I know the devices you bought should work on the UniFi switches. I have the same brand as you put in the screenshot a little bit ago. I just have 5 of the 10/100/1000 model. I also have the model that outputs 5v to a DC jack so I can power my USG 3P via the switch.

They are powering the USG, soon to be cable modem, 4 Chromecasts, 2 raspberry pi 3 B+, 2 echo dots. Working very well after a couple months.

All I did was plug them into ports that had PoE+ active. I am not sure why yours wouldn't be working unless that model has a problem. I did fry one of my pi's while I was walking around on carpet in my basement and I went to move the device and it fried it. I had to buy a whole new board. Do you have another way of powering it besides that adapter?

Have you rebooted your switch? What FW version are you on?

Re: Raspberry Pi via POE

@stekkerdoos, lame check, I know, but you are of course using fully wired (8 wires) ethernet cables, right?

I've never had any problems with the 4 adapters, I own, so I don't know how to troubleshoot.

Re: Raspberry Pi via POE

I hoop the are fully wired.🤪 I used pre fabric patch cabels.

This one is AT

I have had it in my Amazon shopping basket for ages, planning to try it. Haven't gotten around to it yet.

I have the standard POE HAT, the fan drives me nuts....

That looks EXACTLY like the kind of thing I am looking for, even seems to have terminals to tap out to another device (like an LED strip).

 

If you get it, let us know how it goes!

Re: Raspberry Pi via POE

just hit the order button

I bought the AT and AF versions to try out.
