Green circuit board with 40-pin header metal heatsink and cooling fan attached

KEHIPI

KEHIPI PoE HAT (F) development board Raspberry Pi 5 40-pin 802.3af/at

SKU CH-FRJ7-Z95KD

Adds Power over Ethernet to a Raspberry Pi 5 via the 40-pin header with an onboard cooling fan and metal heatsink

  • Powers Raspberry Pi 5 through a single Ethernet cable using 802.3af/at PoE
  • Keeps the board cool with an integrated high-speed fan and metal heatsink
  • Delivers clean, isolated power via a fully isolated switched-mode supply
  • Connects directly to the 40-pin GPIO header for plug-and-play installation
  • Eliminates separate power adapters by combining data and power on one cable

Power Over Ethernet HAT

The KEHIPI PoE HAT (F) is a development board that adds IEEE 802.3af/at Power over Ethernet to a Raspberry Pi 5. It uses the standard 40-pin GPIO header to deliver both data and power through a single Ethernet cable when connected to compliant power sourcing equipment. The board includes a fully isolated switched-mode power supply and an onboard active cooling fan with a metal heatsink for thermal management.

Suitable for Pi 5 network projects

This HAT suits makers and engineers deploying a Raspberry Pi 5 in locations without convenient mains outlets, such as remote sensors, camera nodes or industrial controllers. It requires a network switch or injector that supports the 802.3af/at standard. Builders using older Raspberry Pi models or boards without the 40-pin header cannot use this accessory, and anyone without PoE infrastructure will gain no benefit.

802.3af/at compliance decides fit

The single specification that determines suitability is IEEE 802.3af/at compliance on the power sourcing side. If the available switch or injector does not meet this standard, the HAT cannot power the Raspberry Pi 5. No other voltage or wattage rating is provided, so verifying the network equipment specification is essential before purchase.

Questions about this item

Will the onboard cooling fan on the PoE HAT (F) require periodic cleaning or replacement?

The HAT (F) includes an onboard high-speed active cooling fan with a metal heatsink for heat dissipation; the fan is a moving part that will eventually wear or collect dust, so plan to inspect and clean it during routine Pi maintenance.

What thermal limit is reached first when the Raspberry Pi 5 runs sustained loads with the PoE HAT (F) attached?

The fully isolated SMPS on the HAT (F) and the Pi 5's own CPU throttling point are the two limits; whichever hits its temperature ceiling first will throttle performance, so monitor both the HAT's heatsink temperature and the Pi's reported core temperature.

How much extra heat and noise does the PoE HAT (F) add when the system runs all day?

The HAT (F) converts PoE input through an isolated SMPS and spins an onboard fan, so it contributes its own conversion heat and fan noise on top of the Pi 5's load; expect a measurable rise in case temperature and audible airflow compared with USB-C power alone.
