I am trying to venture into my first mapping platform, but I am reading many mixed things!
I am using this on a aircraft platform, so my RC rails are powered by the ESC's BEC (I will also be using the power block to power the Pixhawk too)
I *Believe* the AUX rails have no power by default, but are shared (and powered) when the ESC's BEC is used.
Now this is where I get confused. My Canon A3400is requires 5v to fire in CHDK.
Does the signal pin fire 3.3v on command from the AUX 7 (My image here is wrong) hence why i have to boost it upto 5v? I am confusing myself as i have read lots of different things using triggers and LED switches and all sorts!
Any help would be amazing! Thank-you
