Note: 1. The C4/104P capacitor in the figure is connected in parallel to the motor rather than placed on the PCB. If the motor is not connected in parallel, a position can be reserved on the PCB.。
2. Compared to the general application of similar products in the market, C1, C2, and C3 in the figure can be omitted, reducing peripheral devices and saving costs.
