Description

Introducing the NE555 Pulse Frequency Duty Cycle Adjustable Module Square Wave Signal Generator, a versatile device that produces a 5V square wave signal.

Ideal for experimental development or driving a stepper motor, this signal generator offers the ability to precisely adjust the output duty cycle to meet specific needs.

It is crucial to understand that while the module permits duty cycle adjustments, any changes will concurrently affect the signal’s frequency. Therefore, modifying one parameter will inherently influence the other, allowing for a dynamic control range over the output signal.

The output frequency range is selectable:
  • LF file: 1Hz ~ 50Hz
  • IF file: 50Hz ~ 1kHz
  • High-frequency file: 1KHz ~ 10kHz
  • HF file: 10kHz ~ 200kHz

The output duty cycle can fine-tune; duty cycle and frequency is not separately adjustable: adjusting the duty cycle will change the frequency;

The output frequency is adjustable:
  • Period T = 0.7 (RA +2 RB) C
  • RA, RB is 0-10K adjustable;
  • Low profile when C = 0.001UF;
  • IF stalls C = 0.1UF;
  • High-frequency file C = 1UF;
  • HF stalls C = 100UF;

so buyers can calculate the frequency of the waveform.

Application:

  • As a square wave signal generator, generates a square wave signal used for experimental development.
  • Used to drive a stepper motor for generating a square wave drive signal.
  • Generate adjustable pulse for MCU.
  • Generate adjustable pulse, to control circuitry associated.
