Adjustable Module Signal PWM Pulse Frequency Duty Cycle LCD Display 1Hz - 150KHz

The module has 4 independent ons to increase or decrease the frequency (FREQ) and the duty cycle (DUTY). If the on is held down, the value will increase or decrease faster.

The values ??are maintained even if the module is disconnected from the power supply.
