For my Arduino i usually power it with a 9v power supply. However i know the Servos i'm using can't handle anything more than 6v (would prefer 5v). Is there something I'm missing for powering the APM with a 9volt BEC or battery?
I've almost got my quad put together and am itching to get it in the air!
Thanks for the help!
5v from the output rail, jumper on. or from the input rail and the out rail needs to be powered. I don't know why i couldn't find it tuesday or wednesday...
You need to look at the schematic. The servo rail powers the Vcc thru a Schottky diode. The Vcc cannot power the servos.
servo power->brain yes;, brain power to servos->no.
I've also noticed that there is a 0.3V drop across the diode, so I'm giving 5.3V to my servo rail, and in turns giving 5.0 volt to the brain.
So to get a little extra speed and power out of the servos can I run 6v from a regulator into the arduplane? Can the regulators in the ardu manage this? Also are the regulators just going to cut it down to 5v anyway or is there a separate voltage for the servo rail.
I am trying to avoid setting up a completely separate voltage/power for the servos and ardu.
