waveshare Power Over Ethernet (PoE) HAT for Raspberry Pi 4B/3B+, 802.3af/at PoE Network Standard, 5V USB-A&12V Header Outputs, PoE HAT Onboard Cooling Fan and MP8676 Buck Chip, Isolated

Works great no issues, if you have overclocked RPI4. Fan of POE may not help to cool down processor.

This hat works great! The 5v usb output and 12v 2 pin outputs have allowed me to add so much cool stuff to my home assistant server that I otherwise would have to use separate power inputs for. Super cool 😎 Only downside is the fan that shipped on the board has bad bearings after only about a week of operation. It's annoying AF, so I usually leave the fan off with the onboard switch. It would be nice to replace the fan with a better one with bearings that don't crap out so soon, but maybe I just drew the short straw.

Hat fits Pi 4B no problems and works as advertised with poe Switch even fits into official Pi 4 case

It works as expected.Worth noting:- M3 distance instead of Raspberry Pi "standard" M2.5- No place for heatsinks on Pi chips, so no overclocking.- Only one fastening point, so avoid vehicle environment.

Tut genau das was es soll.Ich nutze allerdings keine USB Geräte am pi, daher absolut keine Probleme.
