NE555 FREQUENCY GENERATOR

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:

• • 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.

Specifications and Features:

• • Main chip: NE555
  • Input Voltage: 5V-15V DC.
  • Generate adjustable pulse for MCU.
  • Generate 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
  • Input current: >=100 MA
  • Output amplitude: 4.2V V-PP to 11.4V V-PP. (Different input voltage, the output amplitude will be different)
  • Max output current: >=15MA (5V power supply, V-PP greater than 50%), >=35MA (12V power supply, V-PP greater than 50%)
  • Output with LED indication(low level, LED will on; high level, LED will off; low frequency, the LED flashes).
