Adafruit 16-channel PWM/Servo Shield

Hi Community,
I have a big problem with my new servo shield which i bought at amazon.
If i stack it onto my arduino uno the power LED(VCC) lights red. But when I
plug in an external power suplie ( 4 AA batteries 6V) The LED for the exrternal
bateries won´t turn on. It Also smells bad after a few seconds. It smells like something
is burning. I don´t know how to fix this. It would be nice if someon can help.

And sorry for mistakes with my english

one thing to ad. The area around the connector for the power suplie gets very hot, when I connect the batteries

Sounds like a bad board. You should return in for a new one.

The only problem I can think of is if you somehow short-circuited the power block terminal. If you have a multimeter you should check that the + and - terminals are not shorting.
