Overview


This square wave generator uses two potentiometers which can vary the frequency and duty cycle. This can drive a stepper motor square wave signal and can be used to control motors (PWM generator), adjust brightness in bulbs and LEDs or timers. It also features an adjustable pulse control circuit.


Specifications

  • Dimensions: 31 mm x 22 mm
  • Main Chip: NE555
  • Input Voltage: 5 V DC to 15 V DC
  • Signal Frequency: 1 Hz to 50 Hz, 50 Hz to 1 kHz, 1 kHz to 10 kHz, 10 kHz to 200 kHZ (depends on connection date jumper)
  • Current:  ≥100 mA
  • Output Amplitude: 4.2 V V-PP to 11.4 V V-PP (depends on input voltage)
  • Output Current: 15 mA, Vin = 5 V; 35 mA, Vin = 15 V
  • Maximum Output Current:  ≥15 MA


Features

1. Output with LED indication, LED is on when low level, LED is off when high level, LED flashes when the frequency is relatively low;

2. The output frequency range is available in 4 levels, and the output frequency is more continuously adjustable; low frequency range: 1Hz~50Hz, intermediate frequency range: 50Hz~1kHz, intermediate frequency range: 1KHz~10kHz, high frequency range: 10kHz~200kHz

3. The output duty cycle can be fine-tuned. The duty cycle and frequency are not separately adjustable. Adjusting the duty cycle will change the frequency;

4. The output frequency is adjustable, and the frequency of the waveform can be calculated:

Cycle T=0.7(RA+2RB)C (RA and RB are adjustable from 0-10K);

C=100UF at low frequency;

C=1UF in the intermediate frequency range;

Medium and high frequency gear C=0.1UF;

C=0.001UF at high frequency


Precautions

When using the jumper cap to change the frequency, please power off first, and then power on again after the jumper cap is connected.


Scope of Application

1. Used as a square wave signal generator to generate square wave signals for experimental development.

2. Used to generate a square wave signal for driving a stepper motor driver.

3. Generate adjustable pulses for MCU use.

4. Generate adjustable pulses to control related circuits.
