Hello,
I am starting this discussion because I have burned the second APM after connecting a faulty ESC,
I thought the issue was due to a power board, but even with the new power board connected I saw smoke coming out from the smd showed in green in the picture below.
After testing the ESC I found one that was not giving the 5V and that looks in short.
Anyone knows with what I can replace that electronic smd component marked E3C that is placed on top of the I2C port?
