2 Channel Dual Independent PWM Generator Price in Pakistan

  • Two independent PWM generators can set the frequency, duty cycle;
  • The wide frequency range, high accuracy;
  • serial communication option
  • Frequency is divided into three ranges:
  • XXX (no decimal point): the smallest unit is 1Hz, the range 1Hz ~ 999Hz;
  • XX.X (decimal point in ten): The minimum unit is 0.1Khz; the range of 0.1KHz ~ 99.9KH
  • X.X.X. (there are three decimal point): the smallest unit is 1Khz; the range 1KHz ~ 150KHz
  • Frequency display example:
    “100” indicates that the PWM output pulse of 100Hz;
    “54.1” indicates that the PWM output pulse of 54.1KHz;
    “1.2.4.” Indicates that the PWM pulse output 124KHz
  • Duty Cycle in the range: 0 to 100;
  • Three frequencies duty cycle is the same, all the parameters non-volatile.
  • Working voltage: 5–30V, support micro USB 5.0V power supply;
  • Frequency range: 1Hz ~ 150KHz;
  • The frequency accuracy: ± 2%;
  • Output Current: <30mA;
  • Output amplitude: Default 5Vp-p (settable);
  • Operating temperature range: -30 ~ + 70 °.


  • Module has three buttons [Set], [Up], [Down];
  • Press [Set] key to switch the display four parameters (FR1: PWM1 frequency; dU1: PWM1 duty cycle; FR2: frequency of PWM2; dU2: PWM2 duty cycle), before the handover parameters, there will be corresponding parameter name flash.
  • Press [Up], [Down] keys to modify the current parameter value (long press can quickly add or subtract fast).
Two PWM each have three preset frequency, the frequency display interface, long press [SET] key to switch between three types of frequencies, three kinds of frequency duty cycle is the same value. (XXX: range 1Hz ~ 999Hz; XX.X: range 0.1Khz ~ 99.9Khz; X.X.X .: range 1Khz ~ 150Khz,).


  •  As square wave signal generator which generates a square wave signal;
  • to provide a signal to the stepping motor driver;
  • Adjustable pulse generation for chip use;
  • produce variable pulse signal, the control-related circuit (PWM dimming, speed).
  • Fifth, the serial control
  • Baud rate: 9600 bps
    • Data bits: 8
    • Data bits: 8
    • Stop bits: 1
    • Parity bit: none
    • Flow control: none
  • Set the PWM frequency
    • “S1FXXXT”: setting PWM1 frequency of XXX HZ (001 ~ 999)
    • “S1FXX.XT”: set the frequency of PWM1 XX.X KHZ (00.1 ~ 99.9)
    • “S1F: X.X.X.T”: setting PWM1 frequency of XXX KHZ (0.0.1 ~ 1.5.0..)
    • ‘S1’: PWM1
    • ‘S2’: PWM2
    • ‘F’: Frequency
    • ‘D’: Duty Cycle
    • ‘T’ is the end flag
    • Set the PWM duty cycle
    • “S1DXXXT”: setting PWM1 duty cycle XXX; (001 ~ 100)
    • “S2DXXXT”: set PWM2 duty cycle XXX; (001 ~ 100)
    • Setting successful return: DOWN;
    • Setting failback: FALL.
