Hi,
have a new 18v7 simple motor controller (purchased about two weeks ago).
This morning I had inverted Vin-gnd polarity and i think the board is dead.
The controller has not a reverse power protection?
The big capacitor is burn (it stinks) so I replaced it with another one but the motor does not move. USB connection and the control center are ok but when I power Vin the temperature goes up.
