That looks like the exact same one that I was using. “Hardest” part was getting the microusb cable cut and soldering on a coaxial plug for power.

eta: yes, I realize in those pictures the Pi is powered via USB hub, but I found that to be somewhat unreliable and had issues with the Pi, so I ended up bypassing it and plugging the Pi directly into the PoE converter, which resolved a few of the issues. I have since completely removed this set up and have the dongle plugged into my virtual server and connected to a Ubuntu server for processing.
