کاربرد :
از این ماژول به عنوان یک ژنراتور موج مربعی استفاده می شود .
تولید پالس قابل تنظیم برای MCU.
تولید پالس قابل تنظیم، برای کنترل مدار همراه است.
ویژگی :
فرکانس قابل تنظیم .
دارای خروجی با LED نشانگر .(هنگامی که فرکانس پایین است LED خاموش است (چشمک می زند) و هنگامی که فرکانس بالا است LED روشن است ) .
Description
Used as a square wave signal generator produces a square wave signal for the
experimental development use. A square wave signal is used to produce a stepper
motor-driven drive. Produce the adjustable pulse for MCU use. Generates the
adjustable pulse to control the associated circuits.
Technical Specifications
1. The main chip: NE555.
2. Input voltage: 5V-12VDC.
3. The input current: ≥ 100MA.
4. The output amplitude: close to the input voltage.
5. The frequency adjustment range: 0.07HZ-2KHZ (also cycle in about 0.45ms to
15s).
6. Duty cycle adjustment range: 0% to 100% (High / cycle).
7. Output Current: strip 9012 transistor drive capability is strong, about 500MA
output current, the output can directly drive small relays or small motors.
Frequency adjustment methods
1. The board has four the shorting cap can select the frequency.
2. Inserted 0 short-circuit cap, the longest cycle upwards to 0.3 s.
3. Inserted one short-circuit cap, the longest cycle can be adjusted to about
4s.
4. Inserted two short-circuit cap, the longest cycle can be adjusted to about
7s.
5. Inserted three short-circuit cap, the longest cycle can be adjusted to about
10s.
6. Inserted four short-circuit cap, the longest cycle can be adjusted to about
15s.
7. Duty cycle adjustment range: 0% to 100% (High / cycle).
8. Output Current: strip 9012 transistor drive capability is strong, about 500MA
output current, the output can directly drive small relays or small motors.
Advantages
1. Adjustable duty cycle and frequency resolution;
2. Output with LED indication, there is no output straightforward (LED high
amount, low level LED off LED flashes when the low frequency, high frequency LED
will be lit, because the naked eye can not distinguish from)
