Advice for building a new Node Red RPi-3B+ in 2025

 

I have several idle RPi 3B+ units.? But they have only 1 GB of RAM.
My old 2020 RPi3 node-red unit ran just fine with 32bit OS and 32bit .net install.

If I build a new fresh install with Pi OS bookworm right now, I assume I should still
use the 32bit OS, since it is an RPi 3 B+ with only 1GB of ram.
But on this Group's Wiki, the notes for installing .Net aspcore 8.0.13 (latest as of 2/13/25) and FRStack WebAPI 3.8.12.78 (latest as of 2/13/25)
only talk about the 64bit versions.
?
Does this group know the download locations for the 32bit versions of .net and FRStack API,? or in 2025, do you feel that I should no longer
use the Raspberry Pi3, and instead buy a Pi4 with 4GB and install everything in 64bit?
I wanted to try to use the Pi3, since most of the time, the CPU utilization never went above 40%.
?
Looking forward to your mentoring and/or advice.

I will answer my own question.?? I have since learned that trying to run several Node-Red flows,
plus an MQTT Broker, Plus MS DotNet and FRStack APIs on an RPi3 with 1GB of ram will
be.....? PAINFUL.???? I have installed the 64bit OS on an RPi 4 with 4GB of RAM, and am now
starting to install Node-Red, Mosquitto MQTT, DotNET and FRStack.

Node Red does not need much horsepower. I am using it for station control and running it on a RPi Zero2W. It runs just fine on this minimal RPi!
