note:

1. The third yellow interface line is the TTL control line, the voltage range is 3.3-12V, the frequency is 0-20KHz, and it needs to be grounded.

2. The input voltage of the red and black wires is 12V2A, do not connect them in reverse, otherwise the module will be damaged.

3. The power is not controlled by voltage or frequency, it is controlled by duty cycle.
