Just an aside, but I've done this, (put a 5v fan in the box run off of P3)
and I'm very pleased with the results. I used about the smallest and lowest
power fan I could find (.14A, 5.6CFM).

Norm,
That is correct, notice KN-xxx, obviously a KN-50 and it's later
versions
would not, as it would be generically referred to as KN-xx.

Support, does this mean that all KN-XXX boards, including the KN-200
support
this, as long as they are running the appropriate firmware (ie; v4.44 or
higher)?
