LoveRPI POE Compact Hat works great. It was a bit confusing how to attach the hat exactly. Without instructions you have to rely on pictures. In fact, the hat is worn on pins. I am attaching some photos so others can see how the hat is installed. The only downside is if you're trying to squeeze it into a case with a fan, or using a Raspberry that already has a heatsink installed on the processor or memory. There is a square component (capacitor?) that is close to the CPU and is quite high. If you install heatsinks after installing the hat, you can easily move them around to accommodate the hat that covers those components. The fan is a different story. I had to order new frames 30mm high, but that's coincidence. These are minor issues with workarounds. I would probably buy these again. In fact, I'm thinking about doing it right now. I'm addicted to rPi.
