UCTRONICS IEEE 802.3af Micro USB Active PoE Splitter Power Over Ethernet 48V to 5V 2.4A for Tablets, Dropcam or Raspberry Pi 2/3B+ (48V to 5V 2.4A)

Works fine and as advertised. It makes it really easy to hook up a Raspberry Pi as a little server.

Edit: I have two of these and they only worked for about 6 months. They were putting out 5V when they were new, but they both dropped to 4.8V now, which isnt enough to power the cams. I put a Wyze Cam v2 at my front door a month ago. I tried sending 5v over ethernet to the camera, but the voltage drop caused a lot of issues with the camera. So, I put this in with a 48v POE injector (sold separately for $9) and it works great. Features that didnt work before due to the power issue but are working now are: 2way audio, recording to SD card, and IR. I will definitely buy more of these for other cams I put up, maybe even my Raspberry Pi if I put it in a remote location.

This does not pass network traffic only provides power! Anyone looking to buy this so they can only use one wire not two wires. Do not use this for one wire use!

This adapter had an incompatibility issue with the device I was using it with -- however the seller was very responsive and courteous and issued a refund immediately. Ill be clear: i was not using this for a Raspberry Pi, I was using it as a charger for a mobile device. This may still work great for Raspberry Pi devices. Either way, if theres an issue then Arducam will definitely make it right so dont be afraid to buy.

Great splitter but appears to be incompatible with the new Raspberry Pi 3B+.

Works perfect. Im using this to provide power to a raspberry pi from a PoE switch.

I was able to plug the Wyze Camera into this device and make ran POE to the POE Network switch. Alleviating the need to use a power outlet for the USB power brick.

Works as expected. Was able to provide power to the raspberry pi 3 using poe and a cat5 cable only. No separate power supply needed. This was tested with a few different poe capable Ethernet switches.

I dont have any complaints with this item. Ive been using it to power my Pi3 running Unifi controller for the past 4 months or so and havent had any problems. Ill buy more of these in the future.

The POE injector works great if you just want power, but something about this doesnt seem to pass the network connectivity at least for a Pi-3b+/Allied Update: This model of the POE injector (UCT-5159) does not work with the gigabit port on the 3B+. You need to get the updated model (U515902) which DOES support the gigabit port. I purchased this version and it works flawlessly with all of my 3B+s. Attached a photo. The one on the bottom labeled 5V is the one that will not work.
