“Good option if you want to reduce number of cables. Fan is louder than expected , especially if you have multiple pis stacked. In hindsight should have checked non-official poe hat , but overall happy with the purchase”
“So-so. Doesn't provide enough current for some more demanding USB SSD drives etc. It would be better to have an 802.3at model that can provide more power.”
“Quick to install on the Rpi4B, and works as expected! Not seen any voltage drops so far, although I'm not using any USB devices. Bear in mind you'll additionally need risers (2x20 for GPIO and a 2x2 for power) if you use heatsinks on your Rpi.”
“A great add-ons for PI 3B and 4. It is very handy to use as a IOT sensor hub in the green house or garden area where there is no nearby power outlets.”
