“Have used these before, hence my most recent purchase. This PoE hat is very reliable with a low profile. I now have 5 Pi's powered by these PoE hats in a uctronics 5 pi 1u rackmount with SSD brackets. The PoE hat provides enough power to run the pi and usb attached Sata SSD.”
“Brilliant little HATS. Third one I’ve bought now. Solid and reliable. Very compact if you don’t need fan cooling. I run these 24/7 on a BOINC setup, HAM Radio APRS iGate and a FlightAware setup. They don’t seem to produce much extra heat and I use no additional cooling. No setup required. Just plug and play.”
“Purchased two of these as they fitted neatly into the case I was using however when running update commands via ssh they would both reboot. I have since purchased another type which works happily”
