Raspberry Pi PoE HAT

The Raspberry Pi PoE (Power over Ethernet) HAT is a small accessory board for the Raspberry Pi computer. The PoE HAT allows you to power your Raspberry Pi using Power over Ethernet–enabled networks. Please be aware that, for this HAT to work effectively, the network it is connected to needs to have power-sourcing equipment for a 802.3af Power over Ethernet network installed.

No modification to the main Raspberry Pi board is needed for the PoE HAT to work but you will need to ensure that your Pi’s software is up to date for all functionality to be available. The Raspberry Pi PoE HAT is fitted with a small fan that is controlled by the Raspberry Pi via I2C and will turn on and off automatically depending on the temperature of the main processor on your Pi.

Important:The Raspberry Pi PoE HAT can only be used with the Raspberry Pi 3 Model B+ or later (aka. also works with the Pi 4). Every other model of the Raspberry Pi does not have the corresponding PoE pins necessary to operate this HAT.

Raspberry Pi PoE HAT Product Help and Resources

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

    The product states it only works with the Raspberry Pi 3 Model B+ but it actually works with the new Raspberry Pi 4 Model B+ as well.

      Thanks for the heads up. We don't actually carry the Pi 4 yet... however, I will make a note so that gets updated when we get the Pi 4.

Tiny fans are loud, big fans are quiet, otherwise great.

I'm finding that modifying the fan controls to be quite difficult when running Ubuntu MATE on the Rpi, so I'm stuck with the intermittent fan run at 100% which is actually more annoying than if it was just on all the time.

I'm actually considering just hardwiring the fan to gnd/5V to solve it, as a more elegant software solution doesn't seem to exist other than in Raspbian. I run Ubuntu MATE instead due to security concerns in my application, which isn't behind a firewall or nat router, so I have to harden it pretty thoroughly.

Other than the fan noise it's really nice to be able to use PoE for a small network device, like an end point test server/target etc. So for what it's designed for it's excellent, the only flaw is the irritating intermittent fan noise.
