- Users who have bought a HAT and are inconvenienced by this issue should return it for a refund.
That is up to you. My view is here -
You can use a header with long pins to allow stacking a HAT on top of the PoE HAT (this is the only HAT that allows stacking at the moment). It does mean using longer spacers to mount the PoE HAT on the Pi. It would be nice if the header and spacers came as standard or as an option.
There are a number of issues with those tests, scope leads all over the place for example, but the basics are there, just don't rely on the conclusion numbers to be entirely accurate.
You can turn the fan off, it's not necessary for functionality, but will help in some poe applications where heatsinks won't do the trick.rsdavis wrote: ↑Sun Sep 16, 2018 4:56 pmI will be returning these. Too many quality issues. Purchasing the costlier NavoLabs POE hat. See link below. This POE hat is extremely low profile and does not block all of the GPIO pins. Fanless as well. The Pi Foundation POE Hat needs a redesign for following reasons besides USB Issue:
- Fans will fail and I don’t see need for one when heatsinks alone should do the trick.
- Blocks all GPIO pins and therefore hat stacking
