Green circuit board with black cooling fan and Ethernet port

UCTRONICS U611001 PoE HAT with Fan for Raspberry Pi 4 B/3 B+

SKU CH-20YQ-W2GM8

Adds IEEE 802.3af PoE power and a 25 mm cooling fan to Raspberry Pi 4 B and 3 B+ boards

  • Powers Raspberry Pi 4 B and 3 B+ from a single Ethernet cable
  • Delivers up to 12.5 W at 5 V 2.5 A via IEEE 802.3af
  • Built-in 25 mm brushless fan keeps the board at safe temperatures
  • Compact V2.0 design fits tight enclosures and rack mounts
  • Requires an IEEE 802.3af or 802.3at compliant PoE switch or injector

PoE HAT for Raspberry Pi 4 and 3 B+

The UCTRONICS U611001 adds Power over Ethernet to Raspberry Pi 4 Model B and 3 Model B+ boards. It draws power from a compliant network switch or injector and delivers up to 2.5 A at 5 V. The board is aimed at makers and integrators who want a single cable for both data and power in headless or remote deployments.

Compact board with 25 mm brushless fan

The HAT measures small enough to fit inside tight enclosures and rackmount setups without extra clearance. A 25 mm brushless fan mounts directly on the board and can be enabled through Raspberry Pi configuration with a 60 degree threshold. IEEE 802.3af compliance ensures compatibility with standard PoE switches that provide proper electrical isolation.

Replaces separate power supply and passive cooling

This HAT removes the need for a dedicated USB-C or micro-USB power adapter and a separate heatsink or case fan. The upgrade is worthwhile when a PoE switch or injector is already available and the 12.5 W budget covers the Pi plus attached peripherals. It is not suited for setups that lack IEEE 802.3af or 802.3at infrastructure or that require more than 2.5 A at 5 V.

Questions about this item

Does this HAT work with the 802.3af PoE standard and what power does it deliver?

It complies with IEEE 802.3af and supplies up to 2.5 A at 5 V, giving a total budget of 12.5 W.

What physical space does the board and its 25 mm fan occupy?

The V2.0 Mini PoE HAT is a compact add-on that fits directly on the 40-pin header of a Pi 4 B or 3 B+, and the 25 mm brushless fan sits on top without extra brackets.

How do I get the fan spinning after I attach the HAT?

Open Raspberry Pi Configuration, enable fan control, and set the temperature threshold to 60 degrees so the fan starts automatically.
