Raspberry Pi PoE+ HAT (Compatible with Raspberry Pi 4B / 3B+)

The Raspberry Pi PoE+ HAT is an expansion board designed to deliver power and network connectivity to your Raspberry Pi 3B+ or 4B via a single Ethernet cable. It is an ideal solution for educators, makers, and hobbyists looking to streamline cable management in remote or cluster setups.

Single-cable power and data

Compliant with 802.3af and 802.3at standards, this board enables your Raspberry Pi to draw both power and network connectivity directly through an Ethernet cable. This eliminates the need for a separate power supply and reduces cable clutter.

Isolated switch mode power supply

The HAT features a fully isolated Switch Mode Power Supply accepting a 37-57V DC input and delivering a stable 5V 5A DC output. This ensures dependable operation and protects connected hardware from power surges under heavy computational loads.

Integrated brushless cooling fan

An onboard 25mm by 25mm brushless fan actively dissipates heat during high-demand tasks. This maintains optimal operating temperatures between 0 and 50 degrees Celsius to support system stability.

Hardware connection steps

Installation begins by mounting the standoffs at the four corners of the board, followed by aligning the HAT with the 40-pin GPIO and 4-pin PoE interfaces. When disassembling, pull the board evenly to prevent bending the connector pins.

Operating precautions and safety

Ensure the board is used on a flat, non-conductive surface in a well-ventilated environment without obstructing the cooling fan. Use only compliant 802.3af power sourcing equipment and keep the board clear of moisture and extreme heat.
