+- VCC is connected to DC7-40V positive voltage, and GND is grounded. OUT/GND on the right is the PWM signal output terminal.
10
+- OUT is the positive signal output terminal, and GND can be grounded. R5 is used to adjust the output duty cycle. R6 is the output frequency.

+### Adjusting the duty cycle and frequency
24
+
25
+Among them, adjusting potentiometer R5 is to adjust the duty cycle, and adjusting potentiometer R6 is to adjust the frequency. The output frequency is adjusted to more than 700 Hz, as shown in the figure below:

22
+
23
+After the module, + and - 2 ~ 24V, the output voltage can be adjusted by adjusting the potentiometer, the output voltage is greater than the input voltage
24
+
25
+4. Precautions
26
+
27

+## FAQ
36
+
37
+Some customers reported that the module output voltage cannot be adjusted and is always equal to the input voltage.
38
+
39
+If you encounter this problem, please rotate the potentiometer counterclockwise for more than 10 turns, and then use the module to adjust the voltage normally.
