Powering Mio In The Cockpit

I called Mio tech support and they confirmed that number so running the Mio
from a 900 mA port on the 302 should be no problem at all.

- Not sure if the internal fuse of .9A is internally wired to this
particular 5V output. When I tried using my HX4700 with the C302 via
the serial cable, that was wired to provide the 5V out of the 302, the
302 would not function properly. The vario would black out and it
seemed that the ipaq is drawing all the power out if, even though the
input to the C302 had plenty of power. In a nutshell, I did not damage
the C302, but I don’t believe there is a fuse inside - I measured
later that the half charged HX4700 was drawing about 1.5 Amps and C302
would only work with fully charged HX4700 because the lower amp
consumption. Considering MIO tech support is probably located where it
is I would not put too much faith in them especially since you can
damage the C302.

Safe soaring,
