Yesterday during calibration, I fried my second arduino. I believe that this happened due to a very high inside temperature (around 45°) and then the arduino with the shield on top running hot… I haven’t been smarter the second time, but now I am constantly using a fan.
It seems like the ATMEGA2560 chips next to the USB outlet are what is burnt. The crystal next to it (the long silver thingy) is getting really hot.
Now my question is, does anyone have any experience of soldering a new chip onto the board? I don’t like the idea of just buying a new one very much, I want to try and repair as much as possible. Is it close to impossible?
I have found a chip here:
and instructions on how to write the bootloader on the fresh microcontroller:
