Product Overview
Power a Raspberry Pi 3B+ or 4B from a Power-over-Ethernet network, removing the need for a separate power supply and reducing cabling. The HAT includes a fan controlled over I2C that starts slowly at around 40 °C and speeds up as temperature rises for quiet operation.
Key Features
| Feature | Benefit |
|---|---|
| IEEE 802.3at PoE+ | Up to 5 V 4 A from the network |
| Temperature-controlled fan (I2C) | Quiet at low load, cools harder when needed |
| Compact HAT form factor | Sits neatly on top of the Pi |
Applications
| Application Area | Example Projects |
|---|---|
| Networked cameras | Ceiling or wall cameras on one Ethernet cable |
| Servers | Home servers and Pi-hole on PoE switches |
| Digital signage | Screens fed by network and power together |
| Industrial IoT | Sensor gateways in cabinets and ceilings |
| Clusters | Several Raspberry Pis powered from one switch |
Benefits
One cable
Power and network share a single Ethernet cable, so no power socket is needed near the Pi.
Tidy installs
Fewer adapters and cables make ceiling, wall and rack mounting simpler.
Central power control
A managed PoE switch can power-cycle a device remotely.

Please Note
- Requires a PoE+ switch or injector
- Raspberry Pi is not included
- May not fit inside every case — check the case has room for a HAT with a fan
Which PoE Board Fits My Raspberry Pi?
- Raspberry Pi 5 — Waveshare PoE HAT (G), or PoE + M.2 NVMe HAT+ if you also want an SSD.
- Raspberry Pi 4B and 3B+ — Raspberry Pi PoE+ HAT.
- Raspberry Pi Zero series — Waveshare PoE / Ethernet / USB HUB HAT.
- Every PoE board needs a PoE switch or a PoE injector on the network side.
