APM 2 voltage

Posted by Gerry Mostert on March 1, 2012 at 4:56am

Can anyone tell me if it is strictly 5V for the APM 2, or could it go slightly higher. Can not seem to find a regulator which is 5V. They are all about 5.5V or 5.6V. Will the board burn out with this .6V extra?

    Unless they did something really funky/stupid with the board the chips will all be rated at least 5.5V.  ESCs/BESCs usually output 5v, so I don't see why you need a regulator.  Check the board specs also, there's got to be an onboard regulator anyways.

    Hi Gerry,

    An ajustable voltage regulator allows you to use resistors to "adjust" the voltage to whatever you like, and no, 5.5 or 5.6 volts will do no harm to your Arduino.

    Thanks,

    Mark

    YES, do not power with more than 5 volts. Also, some of the analog inputs use voltage dividers and thus higher voltage throws them off too, even if you didn't have component failures directly. Not sure why you cannot find a 5 volt regulator since that's pretty much a standard.
