Product Details:

  • Signal Generator Module
  • Condition: New
  • Scope of this module:
    1 Used as a square wave signal generator generates a square wave signal used for experimental development.
    2 To drive a stepper motor for generating a square wave drive signal.
    3 Adjustable pulse generated for MCU.
    4 Adjustable pulse generation, control circuitry associated
  • Description:
    1 Size: approx.3.1CM * 2.2CM
    2 Main chip: NE555;
    3 Input voltage: 5V-15VDC. When 5V power supply, the output current can 15MA around; When 12V power supply, the output current can 35MA around;
    4 Input current: ≥ 100MA
    5 Output range: 4.2V V-PP to 11.4V V-PP. (Different input voltage cause different output)
    6 Maximum output current: ≥ 15MA (when 5V power supply, V-PP greater than 50%),
    ≥ 35MA (when 12V power supply, V-PP greater than 50%)
  • Advantages:
    1 Output with LED indication, easy to see(low volume LED will light, high volume LED will off, LED flash when frequency is relatively low);
    2 Output level selectable frequency range, the output frequency is continuously adjustable;
    LF file: 1Hz ~ 50Hz
    IF file: 50Hz ~ 1kHz
    Medium-high frequency file: 1KHz ~ 10kHz
    HF file: 10kHz ~ 200kHz
    3 The output duty cycle can fine-tune, duty cycle and frequency can not separately adjustable, adjusting the duty cycle will change the frequency
    4 Output frequency is adjustable;
    Period T = 0.7 (RA +2 RB) C
    RA, RB is 0-10K adjustable;
    LF file C = 0.001UF;
    IF file C = 0.1UF;
    Medium-high frequency file C = 1UF;
    HF file C = 100UF, so you can count the frequency of the waveform
