LORDWORLD Power Over Ethernet HAT POE Type D for Raspberry Pi 3B+/4B 802.3af-Compliant

Power over Ethernet HAT for Raspberry Pi

The LORDWORLD PoE HAT Type D adds IEEE 802.3af-compliant Power over Ethernet to a Raspberry Pi 3B+ or 4B. It draws power from the network cable so no separate USB supply is needed. A fully isolated switched-mode power supply protects the board. An onboard high-speed fan provides active cooling.

Makers needing cable-powered Pi deployment

This HAT suits builders who want a single Ethernet cable to carry both data and power to a Pi 3B+ or 4B. It fits inside the official Raspberry Pi case for a tidy enclosure. Projects that demand more power than the 802.3af class delivers should consider a separate power solution. Users of Pi Zero or earlier models cannot use this add-on board.

IEEE 802.3af compliance and active cooling

The decisive specification is IEEE 802.3af compliance, which defines the maximum power available to the Pi through the Ethernet link. The fully isolated SMPS converts that power safely for the board. The integrated high-speed fan actively dissipates heat generated by the PoE circuitry and the Pi itself. These two features together determine whether the HAT meets a project's power and thermal needs.
