18v7 controller burned

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.


Hi, Mirko.

No, the Simple Motor Controller 18v7 does not have reverse voltage protection. Also, I do not think it would be practical to try to troubleshoot the board, but if you send us an email referencing this post, I might be able to get you a discount on a replacement.
