Description:-

NE555 Frequency Adjustable Pulse generator Module utilizes the NE555 timer IC to generate pulses from about 4Hz to 1.3Khz, which can be used for experimental development, or driving a stepper motor, it would be also a good choice for users learning& experiencing the analog RC circuits.

Features:-

• 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 frequency range is selectable:   

• The output duty cycle can fine-tune;duty cycle and frequency is not separately adjustable;adjusting the duty cycle will change the frequency;

Applications:-

• 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.
