The Official Raspberry Pi PoE HAT was going to make this a niche product till they borked the design (can't use with USB, etc), and now this one is my goto solution for PoE on the Pi. They work a bit differently, so each has it's use cases, but I'll definitely be using this for projects in the future. Seller is very accommodating, for instance I needed to stack other boards with this one, so he left the headers unsoldered so I could select and install my own.
Love them, bought more, will buy more in the future.
The Fe-Pi V2 board is simply perfect: I know that there are quite a few audio boards for the Raspberries, but this one trumps them all (well, at least those that I've been able to find online :) * has inputs!! (Line In and Mic), * very good price, * very easy to set up and works flawlessly (instructions on author's website), * I personally like the chip used (SGTL5000), it's the same one as on the Teensy Audio Board and it's possible to talk to it directly via I2C.
