Re: Power Pi 4 or 5 from 12 volts

 

If you are just running a basic packet system for site telemetry, digipeater, etc, you don't really need a ton of horsepower. An RPi3B+ is normally plenty adequate with a lot less power and cooling issues.

Our club is in the consideration mode for a Pi based packet system with expansion to a VHF an HF RMS. The site has a generator for backup but I know generator power can be dirty and not immediate. We have a 50 amp Astron and I would like to run the Pi from that. Not settled on the verson of Pi but both Pi4 and Pi 5 are in consideration.
So, what would be the recommendation or success stories with a hat based UPS in the pie and what is a good way to power it from the 12 volt Astron?
