Description:
It is used as a square wave signal generator to generate square wave signal for experimental development.
It is used to generate square wave signal for driving stepping motor driver.
Generate adjustable pulse for MCU.
Generate adjustable pulse and control related circuit.
Output with LED indication, whether the output is direct and clear.
The output frequency range is optional, making the output frequency more continuously adjustable.
The output duty cycle can be adjusted slightly. The duty cycle and frequency are not adjustable separately. The duty cycle will change the frequency.
