It Chinese board work but not how you expect.The whole signal-control logic is inverted.On OEM part you have 0v on control pint then motor is on it max speed., 12V or more make motor to stop (OFF position) Here you need 12V over the control pin to run it max. Can be used , but with one NOT logic created using transistor or just by replacing them transistors on oem board you will get problem fixed easy. If mine got broken will change that stupid circuit with one done by FET and PWM
