Now for some unknown reason the vesc does not work at all and the arm chip it’s burning after 5 seconds
probably killed the voltage regulator… or one of the diodes
One question is it worth repairing it ? I mean if it’s not stm32f405(arm) and its dvr or something else ? 
If you fried the STM32 chip, probably not unless you have an STlink to flash the bootloader after repair, as well you’ll need to probe and identify all the components that are bad…
i was looking the VESC ,the transistor has some small “bubbles” and when i plug it , it gets real hot real fast 
, so i think its may be a shortcut, or just a broken transistor , does anyone faced the same problem ?
if anyone has VESC for sale (and willing to send in greece) send me working condition and price , thanks !
