I'm newbie on Raspberry pi. I just want to know, What happen if I power the Raspberry with both the USB and external power voltage simultaneously? Would this burn the controller?

  • You cannot power with USB. Actually your questions is vague; your idea of what things are called does not correspond to any official documentation. – Milliways Apr 4 '17 at 12:21

    I have read the two power sources will "fight" and may cause damage to the Pi powers supply. I suggest you avoid the situation if possible. Why are you doing this? – joan Apr 4 '17 at 12:23
  • @Milliways The assertion that you can't power over USB is somewhat at odds with conventional wisdom. Can you elaborate? – goobering Apr 4 '17 at 12:42

    @DmitryGrigoryev I assume the question is referring to powering via the microUSB socket and the 5V and ground pins of the expansion header. – joan Apr 4 '17 at 14:48

    @goobering The Pi cannot be powered via the USB ports (unless you have already powered it - due to a bug in the circuitry). This question has been given more attention than it deserves, we could guess any of the 100 things the OP is planning and answer them all! – Milliways Apr 5 '17 at 0:04
