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?
