Precautions:

When using inductive loads such as motors, should burnout occur, this indicates the need to incorporate a TVS diode or electrolytic capacitor at the input to absorb high-voltage reverse surges. Motor acceleration and deceleration generate high-voltage reverse surges that may damage the module.
