Feature

●?PWM Pulse Frequency module work voltage range is DC 3.3V-30V; the frequency range is 1Hz-150kHz/1Hz-15kHz; the output current is 5-30mA.
●?PWM frequency supports 2 modes:normal mode & accurate mode.Regular mode with 1% duty cycle steps.Precision mode with 0.1% duty cycle steps.
●?With lock function; PWM output can set frequency & duty cycle separately; duty cycle upper and lower bounds adjustable; support serial communication; all data auto-saved after setting.
●?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; Dimmer; Speed governor, and so on.
●?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.
