Hi there All
I have finally received all the bits and pieces for my tricopter build — plugged in the battery for the first time and the greeting was a little puff of white smoke! I cannot be sure from whence it came, but I suspect the FC.
Following power-down and inspection I notice the following:
Shunt resistor on the FC is hot to the touch ---- I.E. some serious current is flowing
No obvious injured components / shorts visible
When powered up again the FC, and FPV can appear to have no power
ESC’s and VTx are powered
When plugging in USB I the FC powers up and works fine, as does the FPV cam
My suspicion is thus that Schottky diode / regulator has blown.
Further, there is continuity between the GND and 5V+ pins on the Kakute F7 AIO.
Has anyone here experienced something similar / know where on this board I could find the offending components in lieu of replacing them?
