Signal Generator Module Adjustable Square Wave NE555

AED 9.45



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.


  • 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.
Pinout of the Adjustable Square Wave NE555 Module:


  • 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.
Package included:

  • 1 x NE555 Pulse Frequency Duty Cycle Adjustable Module
