New Raspberry Pi PoE+ HAT handles up to 25.5 Watts

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.

Besides supporting 802.3at standard with a higher current/more power, the new PoE+ HAT also adds a current sensor and relies on a planar transformer instead of a wire wound transformer with the former being more compact and efficient.

The brushless fan is controlled by I2C and helps the processor on the Raspberry Pi 3/4. You may need the latest version of the Raspberry Pi OS for the new PoE+ HAT to work properly.

While the Raspberry Pi PoE+ HAT is officially introduced today, it should only be in stock around mid of June 2021, and you should soon be able to pre-order on sites like Cytron, RS Components, Seeed Studio, and others.

‘Bedside’ should better read ‘besides’ and I believe you confused which product uses planar vs. wire-wound.

Note that Waveshare also recently introduced new RPi PoE hats, including one which supports 802.3at (PoE+): https://www.waveshare.com/poe-hat-c.htm

I like that the headers are still available.

They’re going to shove that in an enclosed case with no heatsink and no airflow. What could go wrong? Raspberry Pi hardware “engineering”.
