KEHIPI
A 40-pin GPIO HAT delivers 5 V 5 A to a Raspberry Pi 5 over a single Ethernet cable using IEEE 802.3af/at PoE
The KEHIPI PoE HAT (G) adds IEEE 802.3af/at Power over Ethernet to a Raspberry Pi 5 through the standard 40-pin GPIO header. It delivers a regulated 5 V 5 A supply so the board can run from a single Ethernet cable connected to a compatible PoE switch or injector. Makers and integrators use it to simplify wiring in headless or remote deployments.
The HAT uses a non-isolated switched-mode power supply with an onboard IC for stable conversion. In normal operation the compact module runs without active cooling and draws only the power required by the Pi and attached peripherals. Acoustic noise is negligible because there are no moving parts on the board itself.
A 40-pin GPIO header passes through the HAT, keeping the expansion pins accessible for additional HATs or sensors. The design fits inside the official Raspberry Pi 5 case, so no oversized enclosure is needed. Builders who require isolated power conversion or higher current than 5 A will need a different solution.

Align the 40-pin GPIO header and press the HAT onto the Raspberry Pi 5. Connect an Ethernet cable from a PoE switch or router that supports IEEE 802.3af/at. The step often missed is confirming the network equipment actually delivers PoE power, not just data.
The board uses a non-isolated SMPS with an onboard IC for stable PoE performance. No user-serviceable parts are described. Keep the 40-pin header and Ethernet port free of dust and ensure the PoE source remains compliant with IEEE 802.3af/at.
The HAT supplies 5 V at up to 5 A. Under sustained use the first limit is the current capability of the PoE source; an IEEE 802.3af/at switch or injector must be able to deliver the required power budget continuously.
