⇝PWM Pulse Frequency module work voltage range is DC 3.3V-30V.
the frequency range is 1Hz-150kHz/1Hz-15kHz.
⇝PWM frequency supports 2 modes:normal mode & accurate mode.Regular mode with 1% duty cycle steps.Precision mode with 0.1% duty cycle steps..
PWM output can set frequency & duty cycle separately.
duty cycle upper and lower bounds adjustable.
⇝Square wave signal generator, generating square wave signal for experimental development, generating square wave signal that controls the motor driver, and generating adjustable pulses for MCU Dimmer.
⇝There is no output voltage control. The output voltage is the same as the input voltage. That can be easily changed by adding a simple potentiometer..
