Two Ways to Power a Raspberry Pi Using PoE (Power over Ethernet) 

Great info on Pi and Ethernet!

Appreciate the vid Gary. Nice job.

Very nice and well presented! Great video!

Nice, clear and smooth. Nicely done.

Exactly the information I needed.

very informative! thank you!

Great video and impressed to the simplicity on how you descibe the install. Will this fit in the normal Pi case/housing and perform okay with the fan or will it restrict airflow and require a new vented case/housing?

Another great reason to do this is to add the ability to remotely reboot a non-responsive pi by cutting the POE from the switch and turning back on

Thanks Garry.

Does the hat and splitter handle dropping 48v down to 5v or do you need to use a 5v injector instead of a standard poe switch (48v)?

That’s also useful when you need to power cycle a Pi which is installed in a very inaccessible place or from a remote location.

If you plan to power external drives via USB you really need the PoE+ version of the hat. Otherwise "be careful loading up those usb ports" as Gary explained.

If using the PoE+ HAT, is there enough space between the boards to insert a ribbon cable to the camera ribbon connector on the main Pi board?

The splitter is the winner!

tnx❤

exelent!!!

Why on earth would they design this to cover the GPIO pins? it's the most non-sensical design decision I have seen in a long time.

When can we expect to see a video about Power over Wi-Fi? That would really make my life easier ;-)

is there any good raspberry pi case which can be used with this POE HAT ?

One thing to note is those external PoE adaptors do NOT support gigabit Ethernet. Probably not an issue for what most people use Pi for.

Hi! Im using a Raspberry Pi 4 Model B+, do I need the hat to use the ethernet POE feature?

Hi Gary will a standard poE cable power a sensecap M1 how will it deliver the voltage for that unit. Many thanks stef

*GARY!!!* *Good morning Professor!* * Good morning fellow classmates!* Stay Safe Out There Everyone!

Hi Gary, I liked the video. But could you add a link for power sourcing the POE, e.g. POE injector, to connect the POE hat or POE splitter?

Hi. I absolutely enjoyed this video. Can you make a video about installing arch linux on a raspberry pi please? I tell appreciate your channel. Szabi

Do you need a poe switch for that or a regular switch can do it?

My the new Raspberry Pi PoE+ HAT use for DVR Security Surveillance to control the PTZ Cameras, But I would like to use the ADSL or NBN Broadband Router to Power Over Ethernet by using the TP-Link Powerline Wi-Fi Kit Extend Wi-Fi to Every Room by plugging in the RJ45 Blue or Yellow Network Cable, without using USB C to Power the Raspberry Pi 4 Modal B. So would I need to purchase the 5 to 12 Volt Passive Power Over Ethernet Adapter POE Cable Splitter Injector from eBay.

Ahh, I didn't know POE splitters existed! Just what I need to power up my Pi3b cluster!

Comparing solution costs also would have been nice.

I really hope the next Pi has PoE support as standard.

Another advantage of the last solution (splitting POE into separate data and power) is that it's not restricted to Pi 3B or Pi 4B, correct?

i am trying to work with my raspberry pi 4 but its green led is not flashing ,only red led is working,and nothing displaying on monitor .can you pls help me ,is these bcz of supply issue ,i have given power supply from the usb port of my monitor

Hi! I would love to see a way to power a cluster of Pi 4 over GPIO pin with a Computer PS. How is that made?

Can I pull ethernet from regular WiFi modem to power RPi zero using splitter?

But i need a PoE switch?

Your comments about not being able to use the GPIO pins with a HAT, makes me wornder why no one has ever come up with an intermediate board so you can use the GPIO pins and any HAT. Thanks for the explanation

Usb B mini or micro you just said B

The POE/POE+ HATs are really badly designed. The fan is presumably there to help cool the CPU, since the DC-to-DC converter certainly doesn't need one. But all that really does is restrict your options on dealing with the cpu. For example, many people don't want any noise at all and go for a fanless heat sink. The output is also very poorly regulated. Its an expensive mistake in my view. I would recommend using a POE+ splitter instead. This gives you the most design and build flexibility, far reduced noise (the regulator isn't sitting up against the I/O connector), and more options if you need better regulated output. (Well, the splitter probably has better circuitry inside it anyway. The HAT looks like a mess). In terms of wattage... usually 12W is enough for the RPi and any USB dongles you might plug in short of an external hard drive. I would never connect an external hard-drive powered by USB to an RPI, that's just asking for trouble. Always power such devices separately. The RPi power input is typically limited to 3A (roughly 15W) anyway. You begin to risk burning up traces above those levels. USB keyboards and mice use almost no power (don't use a LED keyboard if you are worried). The biggest usb power hog tends to be wifi power dongles and very high speed memory sticks. People often plug in external wifi dongles (even on a RPI4) because the on-board wifi is really horrible, or there isn't any on-board wifi in the first place. Particularly if you want to use it as a base station or wifi router. Budget 500mA for that. The solution to using very high speed memory sticks is simple... don't use high speed memory sticks. Use medium or low speed sticks. Applications usually have no need for the higher bandwidth. The reason you want to use POE+ instead of POE is because POE+ runs at a higher line voltage (POE is 24V, POE+ runs 48V), thus POE+ has a far lower power loss over long ethernet cables. People running POE over long cables often get far less than the rated wattage at the other end due to losses over the long cable. Also, POE+ has more safety features while POE is just straight-out passive 24V with no handshake or protocol. -Matt

Please reposition the teleprompter

They didn't even need to make 3 of them. The difference is too slim to matter. They could have just made the + model only and been done with it. Just stupid.
