[arm-allstar] 3 nodes on 1 pi

[Dave Petrie]

One more thought, the raspberry pi 3 b plus has the ability to use a wired
Ethernet port, with shielded cat 5 wire and metal connectors for a noisy
environment.
I have had too much interference from wifi routers in the past. Just
thought of it when I was looking over the new pi-zero.
Problem is finding a Pi3 b plus, I can't believe how they have gone up in
price. I am in the process of trying to get a usb to com port on my
raspberry pi 3 b plus
to present itself to my windows 7 computer so i can remotely attach to the
comport on site to program an attached radio, another good reason i like
the raspberry Pi 3 B plus is the number of usb ports.
Happy Holidays
Dave
