Good news re: XT<>RPi

[Marty Roberts]

Hi Brian,

Thanks for the link to the PoE board! 
That’s awesome, and will look at getting that, as I already have a PoE setup for RasPi cameras. It would be even cooler if they made one for Pi Zeros, to reduce the footprint a bit, as well as I don’t need the power of a 4 for what I would do with it. 

Good luck with the rest of it ��

I have a couple of Pis on hand, but no peripherals, so I bought a 3-channel, solid state relay board with POE (RPi PoE & SSR Solid State Relay Board for Raspberry Pi 3B+ 4B) and a POE injector (TP-Link Gigabit 48VDC Passive PoE Adapter (TL-POE4824G). I mated the relay board to a 4B RPi, plugged in the Ethernet cable, and the RPi booted perfectly, powered through the POE circuitry in the relay board. Since I hadn’t used the Pi for more than an year, I brought the OS and apps up to date.
