  • Used as a square wave signal generator generates a square wave signal used for experimental development.
  • Drive a stepper motor for generating a square wave drive signal.
  • Adjustable pulse generated for use by MCU. 4. adjustable pulse generation, control circuitry associated.
  • Output amplitude: close to the input voltage.
  • Duty cycle adjustment range: 0% to 100% (high / cycle).
  • Output current: 9012 transistor strip, therefore drive capacity is relatively strong, the output current can be around to 500MA output can directly drive small relays or small motors; Three Advantages: 1, the duty cycle and frequency resolution adjustable; 2, the output with LED indication, there is no output straightforward (LED high volume, low LED off, LED blinks when the frequency is relatively low, LED will be lit when the frequency is high, because the naked eye can not be seen).

Frequency adjustment range:
Short circuit board has four caps can select the frequency:

  • Insert 0 shorting cap, which is four short cap all remove high-frequency file, the longest period transferred 0.3 seconds;
  • Insert a short cap, the longest cycle can be transferred to four seconds or so;
  • Insert two short cap, can be transferred to the longest period of about 7 seconds;
  • Insert three short cap, can be transferred to the longest period of about 10 seconds;
  • Insert four short cap, can be transferred to the longest period of about 15 seconds;
