Does anyone use PoE for their Pi? Does it have enough juice to run 2 dongle’s for 978 and 1090? I already have a PoE switch so this would save needing an external power supply.
Weird, I've been meaning to log in to check for this EXACT question and if I didn't find it, I was going to post it. Today I finally got around to it, and lo and behold it's the 3rd thread in the Hardware forum right now. Haha. I think I am going to be trying this myself. My consumer-grade Asus router has pissed me off for the last time now that I'm working from home 100% for the foreseeable future and trying to fight for bandwidth from 2 kids iPads playing Fortnight while my work VPN is skipping like mad while I'm trying to have a video conference call with a VP *facepalm*. After spending some time at my in-laws house and being in awe of how smoothly their system works, I have decided to go with a Ubiquiti Unifi system that will also incorporate my houses security cameras. It's going to be a painful wire run (small attic space...Florida heat) to get to where I need the cables to go, but it will be nice to be able to eliminate the wall warts and power strip in the location where my ADS-B and AIS Pi systems currently sit (garage location in multi-fan cases to keep antenna feed lines as short as possible). Per the specs page on the official Raspberry Pi unit (https://www.raspberrypi.org/products/poe-hat/) it puts out [email protected] which is the same as the official AC adapter, so I see no reason why it wouldn't run the same as it currently does on the micro-USB AC adapter. I also run a dual-dongle 978 and 1090 setup, so you're desired setup sounds EXACTLY like what mine will be. Unfortunately, I still need to order a rack for the Unifi system and build the wall that the electric fireplace will be mounted within and the TV will mount onto that I promised my wife I would build that will hide all the wiring, networking, A/V, NAS, PiHole, headless Linux box, and a couple other nerdly devices I run. Running a new 20 amp line off my panel to power it all and also some Cat 6A runs to some Apple TV boxes that currently choke occasionally, so it's going to take more than 1 weekend unfortunately.
I have a RPi running VirtualRadar on PoE. It uses a single Airspy Mini with an LNA/filter in line. Uses a Unifi 8 port switch to power it and it seems to do just fine.
I have an RPi 2B and an RPi 3B, both running on PoE from a Netgear 100Mb PoE switch, using the "PoE Texas GAF-MICROUSB | Gigabit Power Over Ethernet Splitter for 5 Volt USB Power" adapters ordered from Amazon. They seem to be running fine (1 for > 2 years now) and I'm not getting low voltage errors in my logs/console.
