Control

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 12V3A - 12V5A, 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.
