I DID NOT   so I want to know did you connect it wrong as well ????  its easy to blame others !!!
I  believe that the board is…"

"Hi Vital,

Thank you for contacting 3D Robotics Technical Support. Sorry to hear about the damage. Unfortunately when the D4 diode is blown, this typically indicates that the APM was powered incorrectly. Unfortunately, it seems that many components…"

"I have a APM2.5 blow the UART 2 chip has a tiny pinhole on its surface
could it be that the lipo gave too high voltage with JP1 on
I did try to connect the USB to my PC at the same time that the lippo was powering the ESC

could this be a…"

"Hammad  I have the same problem    I have found that UART2   the chip is opposite side of the silkscreen is blown
it has a tiny pinehole in it    as well as the diode just above IC2    

did you plug your USB to your PC with the lippo battery…"

"ok do you think by powering the APM2.5 with the jumper JP1 on meaning that the power comes from the ESC could this be the cause of a failure of the board when a ESC synch is performed connect disconnect etc to the LIPO pack

Is it not then advisable…"

I notice that the diode just above the IC2 socket has a small pin hole    maybe blown  yet seems ok with…"

"did you also perhaps have this problem after calibrating the ESC been  connect disconnect reconnect the Lipo battery pack?
did you use JP1 on?  I have a feel that this is the cause of spikes that damage the board."
