I've been looking forward to the release of a PoE hat. A proper one anyway. I've tried the various available PoE solutions from splitters (which don't work well with a 3B+ due to a passthrough problem with GigE) to the already available PoE hat with the dual nics. None of those provide stable power at the required amperage on a newer model (2 or 3). I have had success with PoE splitters on the original Pi B and B+ and currently use one to supply power and data to my octopi server (original B+ model).

That being said, I don't have a lot of faith this will properly power a pi with any attached peripherals. For $20, I kind of have to buy one.
