I bought a shield for my Nano in order to more easily access the pins of the Nano. Today I tried it and after connecting a 11V power source (battery) to the power connector of the shield it started to smoke and peng something burned through
On one of the images of the upside down Nano you can see an arrow pointing to the burned part. What is it in order to get one and replace it on the board.
Thanks and regards for you comments
Look at the attached images of the shield.
