Hello peepz, So I am having troubles with my boards, starting this weekend i seem to have fried my sainsmart2560 mega8u2, my macbook doesn't find him any more, i tried uploading new software to it but since that didn't work right away i found a cheap mega2560(copy) board so i could continue my work…

Mega2560 problems :( not happy

..seems like you have burnt something..
Id check that external power_source.
is it 7V..12V, positive center, litte or no ripple ?
