Description

Purpose:
  • Generate a square wave signal for experimental development use.
  • Generate a square wave drive signal for driving steppers
  • Generate adjustable pulse for MCU.
  • Generate adjustable pulse for control-related circuit.
Features:
  • Size: 3.1CM * 2.2CM
  • the main chip: NE555;
  • Input voltage: 5V-15VDC. When 5V supply, the output current can be at around 15MA; when the 12V supply, the output current can be about 35MA;
  • the input current: ≥ 100MA
  • the output amplitude:. 4.2V V-PP to 11.4V V-PP (different depending on the input voltage, the output amplitude will be different)
  • the maximum output current: ≥ 15MA (5V power supply, V-PP greater than 50%), ≥ 35MA (12V power supply, V-PP greater than 50%)
Advantages:
  • Output with LED indication, there is no output straightforward (LOW LED quantity, high LED off, LED blink rate is relatively low);
  • The output frequency range of grades available, the output frequency more continuously adjustable;
    • LF file: 1Hz ~ 50Hz
    • IF file: 50Hz ~ 1kHz
    • High frequency file: 1KHz ~ 10kHz
    • High-frequency file: 10kHz ~ 200kHz
  • You can fine-tune the output duty cycle, duty cycle and frequency are not adjustable, adjust the duty cycle will change the frequency
  • The output frequency is adjustable: Cycle T = 0.7 (RA +2 RB) C
    • RA, RB is 0-10K adjustable;
    • At low frequencies file C = 0.001UF;
    • Medium frequency when C = 0.1UF;
    • High frequency file C = 1UF;
    • When high-frequency gear C = 100UF, so the frequency of the waveform buyers can own calculations
