| + | 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 12V, 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. | ||
