Frequency set range:

There is two work mode so it have two frequency range.

Normal mode: Frequency rang e 1Hz~150KHz.Duty cycle rang e 000%-100%.Duty cycle accuracy 1%.
Precise mode: Frequency rang e 1Hz~15KHz.Duty cycle rang e 0.00%-100%.Duty cycle accuracy 0.1%.

Enter the settings interface when short press rotary switch in the normal running statu s to select
frequency range.Rotary potentiometer to set frequency value.
Keep press rotary switch for 10second to switch Normal mode and Precise mode.
Keep press for 5second to locking parameters to protect the parameters from being modified.
Pay attention to the position where the decimal point moves when rotary potentiometer..
Display ‘XXX’.No decimal point, The min imum frequency is 1Hz. The frequency rang e is 1Hz ~ 999Hz.
Display ‘X.XX’. The decimal point is the penultimat e, The min imum frequency is 0.01KHz. The frequency
rang e is 1.00KHz ~ 9.99KHz.
Display ‘XX.X’. The decimal point is the third last, The min imum frequency is 0.1KHz. The frequency range is 10.0KHz ~ 99.9KHz.
Display ‘X.X.X’. The decimal point is fully lit, The min imum frequency is 1KHz. The frequency rang e is 1KHz ~ 150KHz.

Duty cycle set range:

Short press potentiometer to select set duty cycle and rotary potentiometer to set duty cycle value.

Use steps:

• Connect to power supply;
• Press rotary switch for 10second to switch Normal mode and Precise mode;
• Short press rotary switch to set frequency and change value by rotating switch;
• Press rotary switch for 2second to set duty cycle;
• Keep press for 5second to lock set parameters;
• Test;
• Press button ‘ON/OFF’ to turn on or off PWM output;
• Remove power and connect load to use module.
  Application:
• Square wav e signal generator, generating square wav e signal for experimental development;
• Used to generate a square wav e signal that controls the motor driver;
• Generate adjustable pulses for use by the MCU;
• Dimmer;
