Highlights

  • Main chip: NE555
  • Input Voltage: 5V-15V DC.
  • Generate an adjustable pulse for MCU.
  • Generate an adjustable pulse, to control circuitry associated.
  • NE555 Pulse Frequency Duty Cycle Adjustable Module Square Wave Signal Generator is 5 V square wave signal generator. It generates a square wave signal used for experimental development. Also, use to drive a stepper motor for generating a square wave drive signal.
  • 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:

    1. Period T = 0.7 (RA +2 RB) C
    2. RA, RB is 0-10K adjustable;
    3. Low profile when C = 0.001UF;
    4. IF stalls C = 0.1UF;
    5. High-frequency file C = 1UF;
    6. HF stalls C = 100UF;
    7. So buyers can calculate the frequency of the waveform.

Description

  • NE555 Pulse Frequency Duty Cycle Adjustable Module Square Wave Signal Generator
  • Generate an adjustable pulse for MCU.
  • Generate an adjustable pulse, to control circuitry associated.
  • The output current can be 15 MA around; when 12V power supply, the output current can 35 MA around
  • Output with LED indication(low level, LED will on; high level, LED will off; low frequency, the LED flashes).
  • Max Output Current: >= ≥15MA (5V power supply, V-PP greater than 50%), >=35MA (12V power supply, V-PP greater than 50%)
  • The output with LED indication, there is no output straightforward (low LED volume, high LED off frequency is relatively low, the LED flashes);
  • The output level selectable frequency range, the output frequency is more continuously adjustable; LF file: 1Hz ~ 50Hz IF file: 50Hz ~ 1kHz High-frequency file: 1KHz ~ 10kHz HF file: 10kHz ~ 200kHz
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 an adjustable pulse for MCU.
  • Generate an adjustable pulse, to control circuitry associated.
