I am extremely fresh with this stuff (just started tinkering with my first project last week and fried one Arduino already)
I am basically supplying power to the Arduino from the back of my car's rear view mirror. The car's rear view mirror has 12v + ground out. I hooked that up to the Arduino RAW + GND and it fried right away! Reading the docs and MANY other posts before trying this, the RAW pin can take up to 12V and uses the built-in 5V regulator. Apparently, not in my case! What did I do wrong?
I basically need to power 2 servos and trying to not splice any wires. If I use the car's back view mirror to a 5v regulator then to the Arduino, can I hook up to the RAW still and use the other two VCC pins to supply power to 2 servos? I know the bottom VCC in the picture below does power out, but not sure about the VCC on the right if it outputs power too or is just an intake to power the Arduino itself.
If I have regulated 12v to 5v source, can I still connect that to RAW?
