• Module description：PWM output, frequency and duty cycle can be set respectively;
  
  
  
• Normal mode: Frequency range 1Hz ~ 150kHz, duty cycle 000 ~ 100%, duty cycle step 1%
  
  
  
• Fine mode: Frequency range: 1Hz ~ 15KHz, duty cycle: 00.0 ~ 100%, duty cycle step: 0.1%
  
  
  
• The frequency is divided into four ranges, automatic switching:
  
  
  

1. XXX (without decimal point): the minimum unit is 1Hz, and the value range is 1Hz ~ 999hz;
   
   
   
2. The minimum unit of X.XX (the decimal point is in the hundreds) is 0.01khz, and the value range is 1.00khz ~ 9.99khz
   
   
   
3. XX. X (decimal point in ten digits): the minimum unit is 0.1khz; Value range: 10.0khz ~ 99.9khz
   
   
   
4. X.X.X (the decimal point is in the tens and hundreds): the minimum unit is 1kHz; Value range: 1kHz ~ 150kHz
   
   
   

• Frequency display: 100 indicates that PWM outputs 100Hz pulses;
  
  
  
• 1.01 indicates PWM output pulse of 1.01k;
  
  
  
• 54.1 indicates that the PWM outputs a pulse of 54.1khz;
  
  
  
• 1.2.4 indicates that the PWM outputs 124khz pulses;
  
  
  
• Duty cycle value range: 0 ~ 100%
  
  
  
• All setting parameters support power down saving
  
  
  
• Parameters:
  
  
  

1. Working voltage: 3.3 ~ 30V;
   
   
   
2. Frequency range: ordinary mode 1Hz ~ 150kHz; Fine mode: 1Hz ~ 15KHz; 3.Frequency accuracy: the accuracy in each range is about 2%; 4.Signal load capacity: the output current can be about 5 ~ 30mA; 5.Output amplitude: the PWM amplitude is equal to the power supply voltage;6.Temperature: - 20 ~ + 70 ℃.
   
   
   

• Parameter Setting:
  
  
  

1. This product adjusts the frequency and duty cycle by rotating the potentiometer.
   
   
   
2. It can realize rapid adjustment according to the rotation speed.
   
   
   
3. By default, adjust the duty cycle. Short press the adjustment frequency, long press for 2 seconds to lock, and long press for 5 seconds to switch the mode (normal mode / fine mode).
   
   
   
4. The operation is simple. After setting, the parameters are automatically saved and will not be lost in power failure.
