Kk2.1.5 problem

[sahiru]

hey,
I plugged a 11.1v(it was not at 12.6v) li-po to my kk board by mistake. And removed it quickly. Then tried to power up with an ESC. it powers up and first screen comes. safe and others come with missings. Please visit this link and see

I think the board isn't fried. Isn't it? anyway the continuos beeping at the end may be because batt monitor isn't connected.
should I try flashing the firmware?
I could power this board with my 3.7v phone battery before this happend. now I can't.
please help

The link is dead - but I would imagine that you could have done some damage to the board if you plugged over double the voltage.

The good news is: they are cheap (comparatively) and you may be safest to replace it, because you don't want to risk running a damaged flight controller.

I am no expert on flight controllers, but as Motopreserve posted @ double the voltage for which that board is designed (4.8-6.0V) I believe that you "fried" your board.
