don't really remember for that particular version. It doesn't have an
ST202 like the newer ones, so that saves a few mA.</FONT></SPAN></DIV>

color=#0000ff size=2>One advantage of the full-size board is the high-side
switch. It'll control a load up to 30 amps, assuming you keep the duty
cycle reasonable. I used it (with a 9 amp switch) for my resistor-based
cutdown device on my own balloon, though I didn't wind up using
it.</FONT></SPAN></DIV>

<DIV></DIV>Well, I was planning on the KPC-3+, so "light" is relative...
:) <BR><BR>If the weight is down in the grams, then I just might fly it
on a superpressure instead of a solar Montgolfiere - hadn't considered that
there might be something so small! <BR><BR>I assume that the power
requirements for this would be dwarfed by those of the radio and/or GPS -
correct?<BR><BR>Thanks!<BR><BR>Robert KC8UCH<BR><BR>
