@asdrubale bisanzio -- No, the primary becomes a magnet. Calling the ferrite core a "magnet" is like calling the "keeper" placed across the old "horseshoe magnet" a "magnet" since it _conducts_ magnetism. Essentially, calling a magnetic conductor a magnet is like calling the copper wiring in your wall a "generator" or calling the battery cable in your radio (remember radios?) a "battery" since it _conducts_ power from the battery. Or, like calling the subway train "my job" because it takes you to work. N.B.: This does not apply if you happen to be the motorman!

With PoE using a high enough voltage on the cable, things like voltage drop and associated power dissipation can be minimised, so it comes down to the efficiency of the voltage conversion circuit of the power sink/client device. I could see it being theoretically plausible for a PoE switch's bigger, maybe-higher-quality AC-to-DC adapter to have sufficiently improved efficiency compared to the tiny, as-cheap-as-possible power bricks supplied with random consumer devices, that it works out _more_ efficient to use PoE. However I've not run the numbers, nor experimented with it myself, so this is just an idea :)

The idle power consumption is probably due to the planar transformer used. I've seen the idle current double when switching from traditional transformers to those, which would match the findings here. I love planar transformers, but the idle power consumption is a drawback.

Hey Jeff, your PoE+ fan was pretty quiet. I just fitted mine last weekend which sits in an open case. But what I was not expecting was the mosquito sound every 20 seconds then quiet 10-15 seconds and then another 20 seconds of a swarm of mosquitoes - continuously all night long. In the daytime I didn't really notice it but this little chap sits behind a monitor in the bedroom and during the night OMG no sleep that night at all ... So the next day that hat had to be removed :-( Also another gotcha was at the moment there does not seem to be any passthrough GPIO headers for the POE+ hat unlike the old PoE HAT. Due to the POE header is not passthrough. I think all you can do at the moment is to get old POE Long Headers and hack the 4 POE ones down to fit. Btw another great video :-)

Great video, I use a lot of Poe at home, Cisco phones and cctv cameras and back in January I migrated a bunch of services to 4 pi4s and a pi2 this includes homebridge, asterisk and 2 piholes. On my enterprise switch under normal load they pull about 2.2 watts each but when backing up they get closer 5 watts, I don’t have anything plugged in to them except network and the micro sd card. (I don’t need disk performance) since then I have carefully modified the setup using the sd card to boot then creating a mix of sd card ,RAM disk and nfs mounts means backup aren’t needed. The interesting thing is using my Hopi power monitor between the mains and the switch if I keep the Poe power draw for the 4 pi’s under 14w the Poe switch does not seem to draw any more power from the mains compared to no Poe being used. Effectively getting power for free.

Some switch mode isolated DC-DC converters require a minimum load current to maintain regulation stability. This is usually the case with low cost regulators that don’t have an opto-isolated (analogue) feedback and instead they monitor the current through the primary winding during switching to estimate the output voltage.

@alexscarbro796

3 жыл бұрын

That minimum load current could easily be 200mA, so at 5V that’d be 1W. One way to guarantee the minimum load is to place a resistor in series with a zener diode. As the unregulated voltage rises above the zener voltage, it starts to conduct with the resistor becoming a shunt load. This is more efficient than just strapping a load resistor across the regulator output since it only conducts when the voltage drifts too high rather than all the time (which would hurt the efficiency figures under normal loads).

@johndododoe1411

2 жыл бұрын

@@alexscarbro796 If voltage rise is the issue, a zener load that only draws current above 5.2V might (or might not) stabilize the smps. A more complex solution would use a current sensor to reduce or disable the dummy load as actual current draw approaches the minimum. Anyway a well designed PoE+ circuit should have enough complexity to avoid having a minimum load or wasteful own load.

I would love to see your thoughts on some of the other PoE hats for Pi. There are two versions of the LoveRPi Power-Over-Ethernet that might be interesting on Amazon.

Anyone buying a switch today should consider a POE++ or bt standard switch to get lots more power per port. What are your thoughts of the external POE power adapters? I'm thinking of getting something for a Pi4 project and won't have room for the POE hat.

I have a Pi4 ( Raspberry Pi 4 Model B Rev 1.2) with a single 5 TB USB3 spinning hard drive.

I haven't checked the power draws yet, though. (Side note, I went wired ethernet on my OctoPi because the WiFi IP address keeps changing on me for an unknown reason...)

The only actual problem I saw in this video was the screw thing, and maybe the SMT connector... but like you stated, rarely would be an issue. I especially found the USB power test with the hat on to be a weird thing to test for, not that it's bad to test for it, but the way it was framed felt like you were trying to say it was an issue. By the way, I'm sure it was done as a joke, but seeing you saw into that screw still attached drove me insane hahaha.

Hi Jeff, if you run the new PoE hat but set the switch port to run only AF does it still work and does it still consume more power? If I missed this in your video my apologies.

I found using a poe injection kit works better. The kind that break out the browns with two Y cables. Do it for mini hubs in the acoustic ceiling

You can not safely provide DC positive energy from two different sources without connecting the ground (negative) together. Think of it as a voltage difference that provides current. When you connect grounds it ensures the same "voltage difference" is established between the two sources.

When connected to USB-C power, I did not have the Pi plugged into a PoE switch.

I’m curious as to what hard drives could be used with the PoE+ hat without issue? Also, if it is more a throughput issue regards the Pi usb, then surely this isn’t a problem regards the hat but with the USB ports, and if the hard drives are drawing the right amount then it still would be better than the PoE hat which would be incapable of generating enough wattage even if the hat drives were matched to the usb throughput. 🤷‍♂️ I’m a bit of a newb so please correct me if I am wrong I some way.

What are the alternatives? Are there any 3rd party PoE+ hats worth checking out?

Super video! I applauded for $2.00 👏

I have a WaveShare PoE Hat for my Raspberry Pi 4B 8GB RAM model and I find it much better. The WaveShare PoE Hat has a better placement for the fan where it does have a slot to feed through the cable for the camera and also a slot to feed through the cable for display(for screens), It also has a switch to turn on or off the fan, it also has a pass through GPIO where you plug the PoE Hat as normal but at the top of the hat it has GPIO pins on top to connect more things to it. Lastly it also has a USB port on it as well to plug something into it. I also have an extension board for my Pi as well which connects to the audio jack, the 2 micro HDMI ports, and the USB-C port and when it is connected, it gives your Pi the audio jack and USB-C as usual, and you can now use regular HDMI cables to the Pi instead of using the micros and you also get an extra USB port too. I recommend those. If you want I wouldn't mind you reviewing the 2 I mentioned just to get your opinion on it.

They don't think much about their users and their products reflect that, ivory tower syndrome.

Having the same layout for like a decade is pretty good already. Sometimes, designs need to be changed in order to improve a device. They switched to dual micro hdmi ports because a lot (i assume. they wouldn't change it for just a dozen buyers) of customers use rpis for digital signage and wanted to drive two monitors at once, and couldn't fit two full-size ports. I personally think this wasn't a great idea, as the rpi is supposed to be an entry-level computer for learning and hobby projects. Businesses that need to drive multiple monitors for signage can afford more expensive options. Unfortunately, if they change back to regular HDMI now, we'll have a *third* layout that's not compatible with neither 1-3 or 4 cases, so we're probably stuck with those shitty ports for a while.

Thanks for this information and a great video. Why do you use USB C when running Raspberry Pi 4 with POE? are you joking us? (I do not use the word kidding)

If people are needing more than 13 watts to power whatever setup they are running may be the raspberry pi is not the best option. After all, you can get other options in the soc space that offer decent power efficiency with more performance and support for more peripherals without needing to kludge a solution together that may or may not run for the long term. At 15-20 watts idle you are already into intel atom microserver space. The other thing to keep in mind is most rackmount switches, especially PoE ones, consume quite a bit of power as well.

I feel, if you're adding peripherals to your Pi, you can afford having a dedicated power supply too. The only Pis I run on PoE are the one's where I can get away with a single cable to them
