Announcing the Raspberry Pi PoE+ HAT
The Raspberry Pi Foundation has just announced the Raspberry Pi PoE+ HAT compliant with 802.3at (aka PoE+) and 802.3af standards and support for up to 25.5 Watts input.
It will replace the Raspberry Pi PoE HAT introduced in 2018 which was limited to 802.3af standard with a maximum of 15.4 Watts input and will become available around mid-June for $20 plus taxes and shipping.
HAT = Hardware Attached on Top.
Here is a competing Waveshare PoE HAT for Raspberry Pi 3B+/4B.

That can depends on the cluster and its design envelope. It isn't considered completely crazy to have smaller or denser clusters made of low power devices to be PoE. It saves on doubling your wire requirements and simplifies setup, among a couple smaller benefits.
