Small green PoE HAT board with Ethernet connector and GPIO header for Raspberry Pi 3B+ and 4B

LORDWORLD

LORDWORLD PoE Hat (E) for Raspberry Pi 3B+/4B development board

SKU CH-MKR2-4RP79

Adds IEEE 802.3af-compliant Power over Ethernet to Raspberry Pi 3B+ and 4B while fitting inside the official case

  • Fits official Raspberry Pi case without extra space
  • IEEE 802.3af-compliant Power over Ethernet
  • Fully isolated switched-mode power supply
  • Compact component layout for flexible installation
  • Powers Raspberry Pi 3B+ and 4B via Ethernet

Power-over-Ethernet add-on for Raspberry Pi

The LORDWORLD PoE Hat (E) mounts on a Raspberry Pi 3B+ or 4B and draws power from an IEEE 802.3 af-compliant network link. A fully isolated switched-mode supply is integrated onto a compact board that fits inside the official Raspberry Pi case. No separate power adapter is required when a suitable PoE switch or injector is present.

Builders who need cable-free power for headless Pi

This hat suits developers deploying Raspberry Pi units in locations without convenient mains outlets. It will not help builders whose network infrastructure lacks PoE capability or who need to power additional high-current peripherals from the same board.

IEEE 802.3 af compliance

The single specification that decides fit is whether the upstream network equipment supports the IEEE 802.3 af standard. If the switch or injector does not advertise that standard, the hat cannot deliver power to the Raspberry Pi.

Questions about this item

What does IEEE 802.3af compliance mean for powering the Raspberry Pi?

IEEE 802.3af compliance means the HAT draws power from a PoE switch or injector over the Ethernet cable, delivering the voltage and current the Pi needs without a separate USB-C supply.

Which PoE standard does the HAT use and what does it cap in practice?

The HAT follows the IEEE 802.3af standard, so it negotiates up to the power level defined by that standard and is limited by the switch or injector's port budget.

Will the board fit inside the official Raspberry Pi case?

Yes, the compact layout is designed to sit on the 40-pin header and fit within the official Raspberry Pi case without extra height or modification.
