On my bench I have uaefi soldered on an adapter board with only +12v, GND and WBO cable connected

in the beginning I've powered the setup with a (very drained?) battery and things were clicking on start-up
then I've USB and saw a lot of CAN TX err in main MCU tuner studio
then I've added +12v to check if start-up would be not clicking
at some point I've hooked up sensor to the WBO cable

problem: at some point along the way WBO module has died: no blinking, not connecting to st-link

Just assembled another board

Saw red glowing in the corner of stm32f042 while releasing magic smoke.
