There are now multiple PoE HATs available:

I need to choose which one to use for my project.

I already know from reading the product pages in detail that:

  • The Official HAT does not allow to connect other HATS without soldering because it does not pass through the pin header. The fan is said to be quite noisy.
  • The PiSupply HAT cannot do Gigabit Ethernet. (No idea if the other ones can.)
  • Using external PoE splitters (like this one) often produces the same Gigabit Ethernet problem.
  • The LoveRPi HAT is not isolated, and connecting the Pi to another grounded device like a monitor over HDMI will kill the Pi (see product description and Amazon comments).
  • Some other

Beyond this, can anybody provide or link to a proper, full comparison with pros and cons of the options new available for PoE HATs, or at least of the general approaches on which the different devices are based?

  • This is a real depressing list of options. I usually like to use the passive cooling options, but with any of those HATs that's not an option anymore either. – tcurdt Feb 13 '21 at 15:56

    It looks like LoveRPi's now has an isolated option: https://www.loverpi.com/products/loverpi-poe-hat-for-raspberry-pi-4 – kd7iwp Jan 31 '24 at 23:41

Use the official one. While soldering may be a pain, it is possible. You can also replace the fan with another one.
