Please note the following release regarding the PoE HAT from the Raspberry Pi Foundation

A significant proportion of HAT/Pi pairs are limited to delivering <200mA of downstream current to USB. This is generally enough for mice and keyboards, but not for e.g. hard drives. We will fix this issue in a subsequent spin of the PoE HAT. In the meantime we’ll be adding a note where the HAT is sold, documenting this limitation.

We will provide a couple of hand-mod options for adventurous users. These are likely to be:

  • Removing reservoir caps from the main board (an easy, clean mod if you can use a soldering iron, but limits USB hotpluggability).
  • Inserting a small amount of series impedance in the current path from the HAT (this one will be a bit fiddly to implement).

Important note: not all Pi cases are PoE HAT compatible. Please check short video below that should help you to pick right case for your PoE HAT project:
