It is finally here, the official PoE HAT for Raspberry Pi 4 Model B and  Raspberry Pi 3B+, you can power your Raspberry Pi just by using PoE compliance router, network switch or adapter, of course, the Ethernet cable must be connected. As you might have known, the power pins on RJ45 socket (Ethernet) are being extended out to header pins on Raspberry Pi 4 Model B and 3B+. But due to the board size, compatibility and cost, the PoE module is not built on the mainboard. Thus, this HAT is necessary to tab the power from the additional PoE power header pins and convert it to stable power for the Raspberry Pi.

Oh, did I mentioned? It is designed with full isolate Switched-Mode Power Supply (SMPS) which supports the PoE power input range of 37 to 57VDC and converts it into 5V, 2.5A (Max). On top of that, there is a brushless fan pointing at the processor which is controllable via I2C (40-pin GPIO). How awesome is that!

Note: By the way, you can only use it with Raspberry Pi 4 Model B (1G, 2G, 4G) and Raspberry Pi 3 B+, not 3, not Zero, please do take note on that.

Features and Spec:

Packing List:

  • Raspberry Pi PoE HAT
  • Mechanical spacers and bolts

You will need:

Connecting your PoE HAT to the Raspberry Pi

  • Before installing the PoE HAT, you must attach the supplied spacers in the four corners of the board
  • Then connect the Raspberry Pi PoE HAT to the two 0.1” headers (40 + 4) that are fitted on the Raspberry Pi
  • Once the PoE HAT board is connected, you can power the Raspberry Pi through its RJ45 network connector

Disconnecting your PoE HAT

  • Take care when separating the HAT from the Pi
  • Pull evenly so that it detaches from all the pins at the same rate; do not pull one end of the connector off before the other


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

What Pi 4 case can you recommend where the PoE Hat will fit inside and still keeping the Pi cool? ( Kim Hesselholdt, 12/11/2020 )

Hi. You can use this case as this can fit PoE HAT too. Thanks :)

will this work with argon one case? ( Chenhi Edi, 22/06/2020 )
Hi, we're sorry as our team has not tried on that. For further inquiry, you may drop an email to support@cytron.io and our team will reply to you as soon as possible. Thanks :)
Hi Admin, is the POE hat compatible and can be use at Raspberry PI 4 B board? Thanks ( Lee, 24/07/2019 )
Hi, yes it is compatible with Raspberry Pi 4
Hi, can i still using the GPIO pinout after attached the POE HAT on the Raspberry PI 3 B+? If yes, how to connect to the GPIO Pinout? Thanks ( Charles, 24/07/2019 )
Hi, as what we are tested. There is no space to insert the header pin or wire once the POE HAT attached on the Raspberry Pi.
Hi,is there any problem if i use this hat together with 5v raspi adaptor supply? ( Khai, 19/04/2019 )

Hi, sorry we don't have any experience with that but theoretically, there is no problem with that.

may i know the small monitor you use. ( Mohd Azuwan Raspani, 18/10/2018 )

Hi, do you mean Raspberry Pi Display? Please click on this link - Raspberry Pi Display. Thanks.

Hi Admin, roughly when the stock will be coming in and ready? ( Charles, 10/10/2018 )
Hi, we did not know the estimated time yet. Sorry.
