Arduino Nano heats up

Development Tools IDE 1.x
1

Hello Boys and Girls,

I have a Arduino Nano v3.0 that heats up by itself. I wrote some code and tested it on the Beard. Then suddenly the board is not longer accessible by the IDE but the blue LED is still on. When you touch the ATmega with the finger it is hotter than I can resist.

I think it is burned up, but why?

Has anyone experienced that behavior before?

P.S. There is no hardware attached to the arduino board, only the USB cable.

Best Regards

Christian

You blew an output pin, hard to say how, which took out the '328P chip. Replace it.
Maybe a high output pin was shorted to Gnd, that could do it.

Hello CrossRoads,

thanks for your answer. That could've had happend because my desk was a bit messy.

Do you think all i need is a new 328P chip? How can I test the rest of the board?

Best Regards
