Enabling PoE on rock5b without PoE hat

#7

Ah that sounds like a good alternative… so it takes a PoE connection and splits it out to regular ethernet and a usb c connector right?

The problem is looking for one that support 2.5GB input and output and poe+ lol.

#8

You won’t find one. You could use 2 ethernet cables (1 for the POE split and 1 for data) or create a cable from the poe pins to the poe power board.
2.5Gbe POE is too new and most deployments would just use 2.5Gbe injectors for any Acces Point that might require it. The Rock5b is the only device I know of that would need such a thing.

#9

Ah damn… Maybe I would need to use a PoE hat after all.

Is there even such a hat for this yet? I see one for rock pi 4 but I don’t think it’s compatible with 5.

#10

The PoE hat is compatible, but there is no fan control as of yet - perhaps @amazingfate will come up with a solution like they did or the Rock3a :slight_smile:

How is this compatible? The form factor of that PoE hat looks like it will not fit the Rock 5B at all.

I have indeed a rockpi5b and a poe hat ROCK Pi 23W PoE HAT found in :https://wiki.radxa.com/ROCKPI_23W_PoE_HAT. However it doesn’t mechanically fit onto the rockpi 5b board .
so could you please explain how did you manage to use it with a rockpi 5b ?

Actually it does fit on, but you need a different fan which I’ve also tested and got working, but the main concern was the fan position as it doesn’t sit directly above the CPU.

Since then I contacted Radxa and they have informed me that they are indeed making a PoE hat specifically for the rock 5 which will be available in April.

I purchased a different fan and soldered on a Micro JST 1.25mm 2-Pin Connector which is the mechanical presentation on the board, but it’s pointless due to the position of the fan

thanks for your updates ! I will certainly be looking forward for the new poe Hat release !

Any updates on this front?

I’m currently using a USB PD brick to power my two RockPi 5Bs but want to power them via PoE. They’re already connected to a 2.5G PoE+ switch.

The Waveshare HAT works great for me on my 2.5 Gb switch.

Looks like the poe hat is out:

Though my next question is, will I need to download and install drivers for this?

Drivers for the fan? Otherwise what else for? This powers the SBC.

#22

Yeah seems like the PoE hat just works but the fan doesn’t really turn on unfortunately. I think I have to use rsetup.

Hi all. Regarding powering the Rock5B via PoE:

The Rock5B Plus is marketed as supporting Power over Ethernet. Does it actually support it out of the box, or must the Rock5B+ be extended with a HAT PCB? If so which is compatible with Rock5B+ and where buy?

As for photos, could you share some photo of your Rock5B+ or Rock5B equipped with the RockPi 23W PoE HAT and the Waveshare HAT?

Which Waveshare HAT do you mean in particular, one of those listed at https://www.waveshare.com/poe-hat-f.htm ?

For an alternative route, why don’t you just get a “PoE splitter” to USB PD + 2500M or 1000M ethernet?

There does not appear to be any PoE splitter for 2500M ethernet yet. Procet sell one that

Update: This video shows the Radxa HAT on the Rock5B/Rock5B+. Great. https://www.youtube.com/watch?v=IzKJ2_lPxZ8

You can see the PoE HAT is listed as compatible at the end of 5B+ product page: https://radxa.com/products/rock5/5bp

#25

Is there any plan to design a high power board? maybe POE++ (802.3 bt) to power the board when it has full peripherals?

#26

It will be huge and/or loud to cool 90W power supply.
