Obviously, the higher power version(s) [there is also an 80W version]
provide the 12V by feeding through the switched supply; the real work is
in the 5V and 3.3V supplies. Unless one of the boards uses a lot of 12V
current, which Lyle was _not_ going to do, there is likely no difference
from our perspective => picoPSU-60-WI is the right one for us, I think,
subject to noise considerations.

It makes ZERO sense to start with 12V and go thru a 12V-to-12V DC-DC
converter for high current applications. Of course, you should feed the
power-hog RF widgets direct from the RAW 12V source.<br>
