LORDWORLD PoE HAT (D) with Fan for Raspberry Pi 3B+/4B

SKU CH-NFM2-EF8Z6

A PoE HAT for Raspberry Pi 3B+ and 4B with IEEE 802.3af power, isolated SMPS, built-in cooling fan and official case compatibility

  • Powers Raspberry Pi 3B+ and 4B through the network cable
  • IEEE 802.3af compliant PoE removes the need for a separate power supply
  • Fully isolated switched-mode power supply protects the board from voltage spikes
  • Onboard high-speed fan actively cools the processor under load
  • Fits inside the official Raspberry Pi case without modifications

PoE HAT (D) with Fan for Raspberry Pi 3B+/4B

This add-on board supplies power to a Raspberry Pi 3B+ or 4B through an Ethernet connection. It draws power from any IEEE 802.3af-compliant network switch or injector. A fully isolated switched-mode supply regulates the voltage for the Pi. An onboard high-speed fan provides active cooling for the main processor.

Makers adding PoE to Pi 3B+ or 4B projects

The HAT suits builders who want a single cable for data and power and who use the official Raspberry Pi case. It is not suited for users of other Pi models such as the Pi 5, Pi Zero or earlier boards. Projects that rely on passive cooling alone will not benefit from the fitted fan. Anyone needing a different power standard must look elsewhere.

IEEE 802.3af PoE standard compliance

The board accepts power only from equipment that follows the IEEE 802.3af specification. Supplying power from a non-compliant injector or switch will not work. This single requirement decides whether the HAT can be used in a given network installation.

Questions about this item

How noisy or hot does the onboard fan make this PoE HAT (D) when the Raspberry Pi runs all day?

The board includes an onboard high-speed active cooling fan designed for better heat dissipation during continuous operation.

What must I already own to use this PoE HAT (D) with my Raspberry Pi?

You need a Raspberry Pi 3B+ or 4B and an IEEE 802.3af-compliant Power over Ethernet network switch or injector to supply power through the Ethernet cable.

Will this HAT fit inside the Raspberry Pi official case I already use with my 4B?

Yes, the PoE HAT (D) is compatible with the Raspberry Pi official 4B case, so it fits alongside the board without modification.
