This is an 802.3af compliant Power over Ethernet (PoE) HAT for the Raspberry Pi, featuring a built-in fan and a 0.91" OLED display for monitoring temperature, IP address, fan status or anything else you want to show!
The HAT's cooling fan allows auto running on boot or programmable control, configured by the switch to automatically turn on/off depending on the Raspberry Pi's processor temperature.
By using this small HAT and some proper 802.3af-compliant power sourcing equipment, it is possible to provide both network connection and power supply for your Raspberry Pi with a single Ethernet cable.
Compatability
This product will only work with the Raspberry Pi 3B+ or Pi 4. Not compatible with Raspberry Pi 5.

Power over Ethernet HAT for Raspberry Pi 4/3B+
Does what it says on the tin, doesnt appear to occupy the gpio port since it gets extended thru the hat via its own header. the OLED display/fan takes some fiddly set up to get working including light editing and recompiling of the provided example c programme if you want to flip the screen, or set a custom fan threshold so its not exactly one click, but it cant be too difficult if i manged to work it out.

Power over Ethernet HAT for Raspberry Pi 4/3B+
Got them and they are quick and easy to install and do power my PI 4 via the ethernet cable but the little screen on them do not work. I dont know if this is down to what type of software you are running (64bit PI) but i cannot get them to come on. When the switch is in the PO position.

Power over Ethernet HAT for Raspberry Pi 4/3B+
I was wanting a POE hat, as I'm trying to cut down on the morass of wires around my desk. My Pi4 is a hobby toy and training tool and PoE is another great thing to learn about.
Took about 15 minutes to get up and running, including all the software to make the small OLED display work. Unlike some other PoE I've read about, this seems to be silent and ... just works very well. It's really useful having the IP address display on the white OLED screen.

Great Hat wish it was a bit lower profile but works great, just add this script https://gist.github.com/CharlesGodwin/adda3532c070f6f6c735927a5d6e8555 and it will work great

Power over Ethernet HAT for Raspberry Pi 4/3B+
It works out of the box, quite a really nice
THe only 'but' is the example script, it cannot work on boot if using rc.local, just stop because it cant take the local ip, as somebody says before, adding a 30 secs delay does the trick
