Raspberry Pi PoE HAT Expansion Board

Power over Ethernet (802.3af Class 2): Delivers clean 5V / 2.5A DC power and high-speed network connectivity to compatible Raspberry Pi boards via a single Ethernet cable.

Integrated Brushless Cooling Fan: Features a small, temperature-controlled brushless cooling fan that automatically activates to cool the main Raspberry Pi processor during heavy workloads.

Fully Enclosed Flyback Power Supply: Built with a fully isolated switched-mode power supply (SMPS) for high efficiency, voltage regulation, and safety compliance.

Seamless Board Stacking: Mounts directly on top of the Raspberry Pi 4B/3B+ 40-pin GPIO header and dedicated 4-pin PoE header, leaving a compact, single-unit footprint.

Plug-and-Play Network Setup: Operates natively with standard Power over Ethernet (PoE) power-sourcing equipment (PSE) such as PoE switches and active injectors.

PCB Composition: Constructed on a high-density FR4 fiberglass printed circuit board with surface-mounted components designed for continuous indoor operation.

Fan & Heatsink Maintenance: Keep fan blades clean and free from dust accumulation using compressed air. Avoid touching or applying physical pressure to the fan hub.

Static Handling Precautions: Standard electrostatic sensitive device (ESD). Hold by the fiberglass outer edges and ground yourself prior to installation on the Raspberry Pi header.

Environmental Limits: Recommended operating ambient temperature range is 0C to 50C . Protect from moisture, liquid condensation, and conductive metallic debris.

Single-Cable Infrastructure Pitch: Market heavily to home-lab enthusiasts, IT administrators, and IoT builders looking to eliminate separate AC power bricks and clean up cable management.

Ideal for Remote Deployments: Position as the ultimate expansion board for remote security cameras, network monitoring nodes, wall-mounted dashboards, and rack-mounted Pi clusters.

Recommended Accessories: Cross-sell active 802.3af PoE Switches, PoE Injectors, and CAT6 Shielded Ethernet Cables to ensure customers have the required power-sourcing equipment.

Compatibility Callout: Highlight compatibility with 4-pin PoE-enabled boards such as the Raspberry Pi 4 Model B and Raspberry Pi 3 Model B+.
