คุณสมบัติเพิ่มเติมโมดูลสร้างความถี่ NE555 Pulse Frequency Duty Cycle Adjustable 

• Size: 31mm * 22mm;
• Main chip: NE555;
• Input Voltage: 5V-15VDC. when power supply is 5V , the output current can be 15MA around;when 12V power supply, the output current can 35MA around;
• Input current: >=100MA
• Output amplitude: 4.2V V-PP to 11.4V V-PP. (Different input voltage, the output amplitude will be different)
• Maximum 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);
• The output requency 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.

NE555 Module 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.
