Specifications:

  • Working voltage: 3.3~30V ;
  • Frequency range: 1Hz~150KHz ;
  • Frequency accuracy: the accuracy in each range is about 2% ;
  • Signal load capacity: the output current can be around 5~30ma ;
  • Output amplitude: The PWM amplitude is equal to the supply voltage;
  • Ambient temperature: -20~+70 °C.


Features:

LCD liquid crystal display frequency and duty cycle, very clear, PWM output can be set separately frequency and duty cycle;
Wide frequency range and high precision;
Serial communication

The frequency is divided into four ranges and is automatically switched:

  • 1. XXX ( no 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 hundred digits) is 0.01Khz , and the value range is 1.00Khz~9.99Khz ;
  • 3. XX.X ( decimal point is ten ) : The minimum unit is 0.1Khz ; the value range is 10.0KHz~99.9KHz
  • 4. XXX ( decimal point in ten and hundred ) : minimum unit is 1Khz ; value range 1KHz~150KHz

Frequency Display:

  • 100 means PWM output 100Hz pulse;
  • 1.01 indicates that the PWM outputs a pulse of 1.01K ;
  • 54.1 represents the PWM output 54.1KHz pulses;
  • 1.2.4 indicates that the PWM output is a pulse of 124KHz ;
  • The duty ratio ranges from 0 to 100% ;
  • All setting parameters are saved after power down.


Applications:

  • Used as a square wave signal generator to generate a square wave signal for experimental development;
  • Used to generate a square wave signal that controls the motor driver;
  • Generate adjustable pulses for use by the MCU ;
  • Generate adjustable pulses and control related circuits ( applications such as PWM dimming speed regulation).
  • serial port control (microcontroller TTL level communication)


Communication Standard:

  • 9600 bps data bits : 8
  • stop bits : 1
  • check digit : none
  • flow control : none

Instructions:

  • set the frequency of the PWM
  • “F101”: Set the frequency to 101 HZ (001~999)
  • “F1.05”: Set the frequency to 1.05 KHZ (1.00~9.99)
  • “ F10.5 ”: Set the frequency to 10.5KHZ (10.0~99.9)
  • “F1.0.5”: Set the frequency to 105KHZ (1.0.0~1.5.0)
  • Set the duty cycle of the PWM
  • “DXXX”: Set the duty cycle of PWM to XXX ; (001~100)
  • For example, D050 , set the PWM duty cycle to be 50%.
  • read the setting parameters
  • Send a " read " string and read the set parameters.
  • Set the success to return: DOWN ;
  • Setting failed to return: FALL .
