Electrolytic here is too slow to suppress static and if they are too big they'll dissipate power and degrade and eventually die with a bang; besides they can't handle reverse polarity. The electrolytic I referred to i would put over the 5V power line, just to be able to bridge short power dips. I believe I have 300µF here.
Thank you that's clear, so I guess I should solder these back to the motor ... I thought it has to do with the St2000 board so I removed them.
