CANtieCAR / Re: V4 getting hot after 5-6 m...

Last post by Oleksandr - February 13, 2021, 15:03:55

look a like hard broken
recheck all transitors in sot-23 package marked as 6C and 5C and diodes WW1
there is couple of them with crack holes due to breakage
look on ICs MAX4664 for the same damages
one of them can be hot because it is broken
really there are many damages can caused the errors...
