UCTRONICSPoE Splitter Gigabit 5V - Micro USB Power and Ethernet to Raspberry Pi 3B+, Work with Echo Dot, Most Micro USB Security Camera and Tablet - IEEE 802.3af Compliant

Simple solution for the older Pi3 (or Pi2 for that matter) models that do not have the pin header for a "HAT" and, in addition, does not interfere with a case (as the HATs do) for obvious reasons so even if you have a newer model this might be a better answer depending on what you need and want. Works well; plug it in and off you go.

Works great, as expected. These things are handy, if you have a lot of 5v devices to run and you have a powered network switch you can eliminate power bricks from the wall or power bar.

Work perfectly on my Raspi 2B+ and 3! powering motioneye os with one cam and the other small touch screen to receive video feed from the other pie with the cam.

I purchased a UCTRONICS PoE splitter in order to power a Raspberry Pi at a distant location (the location on my property where my cellular hotspot gets excellent reception, where the Pi can use a wifi bridge to ethernet and send the signal to my house as my primary internet). Performance beyond 10/100 was a priority, as in this location I can get 150 Mbps. After testing out my setup with an extension cord, I needed a way to power the system without running another cable out.Enter the UCTRONICS Poe splitter. My splitter arrived, and after extensive testing (with a TP Link PoE switch; with several individual PoE injectors; with several cables), I came to the conclusion that my splitter didn't work, and needed to go back. I usually reach out to the sellers first in case I've missed something (while this device seems fairly straightforward, perhaps my injectors / switch were incompatible?). Arducam, the seller, responded extremely promptly, and sent a replacement splitter immediately - showing up two days later. This new splitter worked exactly as I hoped - gigabit speed, 2.4A output, plug-and-play, and worked with all of my injectors. It's also smaller than many of my other brand of PoE splitters, so works better in the enclosure I've put it all in.I've had devices arrive from small to big manufacturers that haven't worked, devices which have been excellent when I have a replacement. It all comes down to the response from the company involved, and my star rating reflects the working device and the excellent and prompt replies from Arducam to get a replacement out to me. Thank you Arducam!

UPDATE 2/26/2019: Since my original review I have purchased many more of these PoE splitters and they have all worked flawlessly even for the more power hungry Raspberry Pi 3 B+. The first one I installed has been working for 4 months now and it is on a Raspberry Pi 3 B that has been running 24/7 due to the nature of the application I am using it for. Next week I am scheduled to deploy 6 more of these. If you need to power your Pi via PoE, you need this splitter.Original Review:I have multiple Raspberry Pi driving a 21.5 inch touchscreens that staff is using to do documentation on web based applications. In one location I do not have an outlet nearby and the 5V power supply cannot be extended much because of the voltage drop. So I used a 12V power supply and a 5V regulator but the raspberry was displaying a lightning icon on the upper right corner of the screen which means that it has a power issue and the touchscreen would not respond for a couple of seconds now and then. I tried 3 different 5V regulators and the problem would go away for a few days only to return along with the user complains. I believe that the regulators were failing to supply the required amps while the voltage was stable but a bit under the 5V mark (about 4.9 Volts). I was about to get an adjustable regulator and push it to 5.2V but I saw this PoE splitter and I figured, I will give it a try.We had a Netgear ProSafe GS108PE in the server room that was feeding 2 access points and it is about 100 feet away so I plugged this in one of the 4 PoE ports of that switch. It worked flawlessly immediately and it has been 3 weeks now that I have not heard any complains. I asked one of the users about a week ago and he told me that it has been working without any problems.I will be ordering many more as this saves me from having to find outlets for the Raspberry Pi and I have to install another 23 of them. Great product, good price... Highly recommended.
