Package List: 1 x Motor Controller Note: 1. The input voltage should be equal to the rated voltage of the motor. It is not possible to input household electricity. 2. The input must distinguish between positive and negative polarity. 3, The motor can be divided into negative, when the running direction is inconsistent with the expected, you can change the direction by adjusting the motor wire sequence
