I don't know how, but at 3.3 volt regulator(LD3985M33R) burnt .
STM32 chip have some overheating.
What else could be damaged?
Is there a chance that it will work if I replace the stabilizer?
So what i have now it is no led's light and no communication.

cannot find the picture of my 10+ dead discovery boards. I've just accepted this as part of life, even while it happens less often now. See also

Was this something you did, or could this be related to some currently unknown flaw? I'm looking to learn if there is an issue that can be resolved by changing the Frankenso hardware PCB.

I tried to use the CAN bus,after some connections via USB the led's have begun to lose brightness and then shut down.
After all I took out the STM Discovery from the board Frankenzo, and tried to connect to my laptop via USB.
LD3985M33R was very hot!
STM32 chip becomes warm after a while.
And no communication
