This module is Based on the famous NE555 chip used as a square wave signal generator in your prototype process circuits to generate square wave signals for experimental development or as an adjustable pulse for microcontroller applications, such as operating stepper motors.

Specifications:

• Generates a square wave signal for experimental development as a square wave signal generator.
• It is used to generate a square wave drive signal to drive a stepper motor.
• Create a variable pulse for the MCU.
• Create an adjustable pulse to regulate the circuitry.
• Dimensions: 31mm x 22mm
• NE555 is the main chip.
• 5V-15V DC input voltage When the power supply is 5 V, the output current may be approximately 15 MA.
• when the power source is 12 V, the output current can be around 35 mA.
• Output amplitude ranges from 4.2 to 11.4 volts V-PP. (If the input voltage is variable, the output amplitude will also vary.)
• Maximum output current: >=15MA (5V power supply, V-PP larger than 50%), >=35MA (5V power supply, V-PP greater than 50%). (12V power supply, V-PP greater than 50 percent )
•  LED indicator of output (low level, LED will on; high level, LED will off; low frequency, the LED flashes)
• You may choose the output frequency range:

1. 1Hz – 50Hz LF file
2. 50Hz – 1kHz IF file
3. 1 kHz to 10 kHz high-frequency file
4. 10kHz to 200kHz HF file

• The output duty cycle may be fine-tuned; the duty cycle and frequency cannot be adjusted independently; changing the duty cycle will affect the frequency.

 

• Used as a square wave signal generator, it offers the square wave signal for the use of experimental development.
• Used to produce driving stepper motor drives, offer the square wave signal.
• Adjustable pulse for the use of MCU.
• Generate adjustable pulse control circuit.

• 
  1 x NE555 Pulse Frequency Duty Cycle Adjustable Module
