Module description

One-channel PWM output, wide frequency range and the duty ratio can be adjusted.
Frequency is divided into four areas, automatic switching:

  • XXX(No decimal point): 1HZ Stepping Unit,Range:1Hz~999Hz;
  • X.XX(The decimal is in the hundreds place):0.01KHZ Stepping Unit,Range: 1.00Khz~9.99Khz;
  • X.XX(The decimal is in the tens place):0.1KHZ Stepping Unit,Range: 10.0Khz~99.9Khz;
  • X.X.X(The decimal is in the ones place):1KHZ Stepping Unit,Range: 1Khz~150Khz;

e.g. ,frequency display:100 represent the pulse of 100Hz ;

  • 1.01 represent the pulse of 1.01KHz; 
  • 54.1 represent the pulse of 54.1KHz
  • 124 represent the pulse of 124Hz

The value range of dutyfactor: 0~100%,100% is represented by A0%.
All parameters setted up can be automatically saved in case of power cut.


Parameter settings

The module has 4 independent keys with double function, used to set the frequency and duty ratio, a short press (increase or decrease a unit) and long press (fast increase or decrease), very simple, set the parameters automatically and save on power loss.


Scope of application:

  1. Used as square wave signal generator to generate square wave signal for experiment and development aplications
  2. Used to generate a square wave signal to control a motor driver;
  3. Generating adjustable pulses for MCU use;
  4. Generate adjustable pulse, control related circuit (PWM dimming speed and other applications).
