Raspberry Pi PoE+ Injector

The Raspberry Pi PoE+ Injector is a single-port 30W injector suitable for powering devices conforming to the IEEE 802.3at and 802.3af specifications, including all generations of the Raspberry Pi PoE/PoE+ HAT.

The injector supports network pass-through at 10/100/1000Mbps speeds.

A PoE HAT is required to use this device to power a Raspberry Pi 3B+/4/5 over PoE. Raspberry Pi do not currently offer a PoE HAT for Raspberry Pi 5, however some 3rd party Pi 5 PoE options are available.

A power cable is not included. You’ll need a ‘kettle-type’ IEC C13 cable, which we stock in the store. See the section below for links for different regions.

Power cable not included

The injector is sold without an EIC mains lead (known as a ‘kettle’ lead). We offer these in the store if you don’t already have one in your box of cables at home:

• UK 3-pin IEC C13 power cable
• EU 2-pin IEC C13 power cable
• USA 2-pin IEC C13 power cable

How do PoE injectors work?

PoE injectors work by ‘injecting’ power into an RJ45 Ethernet cable along with your data lines (internet connection).

You plug in your standard Ethernet cable for data, along with a power cable (IEC kettle-type) for power, and then the injector merges these into a single RJ45 Ethernet output to run to your device via another RJ45 cable.

This allows both power and internet data to pass through a single RJ45 cable, which is then ‘split’ at the other end, using a PoE splitter or dedicated PoE HAT.

Why would I want to use PoE?

PoE is really handy for removing the need for a wall socket where your end device/project is (hence why it’s so popular for CCTV cameras as they’re rarely mounted near a wall socket).

It’s also a popular choice for those running lots of devices/Raspberry Pi boards in a single location like a server rack, as it removes the need for lots of individual plug sockets and power supplies (a PoE switch as the injector is generally the better option here though).

Which Raspberry Pi boards support PoE?

There are a few models of Raspberry Pi that support PoE when used with a PoE HAT (they have special pins on the board to accommodate the HATs):

• Raspberry Pi 3B+
• Raspberry Pi 4
• Raspberry Pi 5

However, you can power other non-PoE Raspberry Pi models by using a dedicated splitter with the correct power cable. For example, to power the original non-PoE Raspberry Pi 3B with PoE, just use a Micro-USB PoE splitter.

I’m already using a HAT on my Raspberry Pi, does this mean I can’t power using PoE?

You can still power your Raspberry Pi using PoE, you’ll just need to use a standalone PoE splitter rather than a HAT.

For example, to power a Raspberry Pi 5 via PoE without a PoE HAT, you can use something like this USB-C Gigabit PoE 5V 5A splitter. Or for Raspberry Pi 4 with lower power requirements, you can use this USB-C Gigabit 5V 2.4A version.

Another option is to stack your HATs with a stacking header, such as this stacking header designed for the official PoE+ HAT.
