Review on 💡 UCTRONICS Raspberry Pi 4 PoE HAT: Power Over Ethernet Expansion Board for Raspberry Pi 4 B and 3 B+ by Juzer Rashid

Pros: * It works * It provides enough power to power a 7 inch touch screen * It is very easy to attach * Super slim * Keeps access to (almost all) contacts on the PiCon * It cannot negotiate with my (slightly older) Nortel/Avaya PoE switch. It flashes for a second and then goes off again. Instead, it works well with Unifi's PoE injector. *No pins were provided for the 5V/Gnd pins it covers on the Pi. I had to take my own and solder them. A 2 minute challenge as I had them in stock and have experience with them, but it's frustrating that a) they don't come with pins or b) they are pre-soldered. I need them to power the touchscreen directly.
