Raspberry Pi PoE+ HAT for 3B/4 | Power Over Ethernet Add-on
Raspberry Pi PoE+ HAT for 3B/4 – IEEE 802.3at, 5V 2.5A Output
The Raspberry Pi PoE+ HAT is an official add-on that enables Power over Ethernet capability on compatible Raspberry Pi models. It allows you to power your Pi and provide network connectivity through a single Ethernet cable, simplifying cabling and enabling deployments in hard-to-reach places. This HAT delivers up to 2.5A at 5V, sufficient for the most power-hungry Pi applications.

Compatibility
Designed specifically for Raspberry Pi 3B+ and Pi 4 models with PoE header pins. Not compatible with older Pi models (3B, 2B) that lack the 4-pin PoE connector. Works with standard 802.3at PoE+ switches and injectors. For Pi 4, ensures stable power even under heavy CPU load and USB peripherals.
Wiring Notes
The HAT connects via the 40-pin GPIO header and the 4-pin PoE header near the Ethernet jack. No additional wiring is needed; simply align and press down. Ensure the fan is mounted to blow onto the Pi's processor for optimal cooling. Use a good quality Cat5e or better cable with a PoE+ switch rated for 30W per port.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Raspberry Pi 5?
The PoE+ HAT is not officially compatible with Pi 5 due to different pin arrangements; Pi 5 requires a newer PoE HAT.
Can I use this without a PoE switch?
Yes, you can use a PoE injector that plugs into a standard Ethernet port and adds power, with a second cable to the HAT.
Does the fan run continuously?
The fan is PWM controlled based on temperature; it may run at low speed when the Pi is idle and ramp up under load.
