Product Description


    Product Introduction:
    1.Operating Voltage:5-30V;support micro USB 5.0V power supply 
    2.Frequency Range:1Hz-150KHz
    3.Frequency Precision:2%
    4.Signal Load Capacity:8-30mA 
    5.Output Range:5V
    6.Ambient Temperature;-30~70 Celsius
    1.Two independent PWM generators can set the frequency,duty cycle
    2.The wide frequency range,high accuracy
    3.Support serial communication.
    1.As square wave signal generator which generates a square wave signal
    2.To provide a signal to the stepping motor driver
    3.Adjustable pulse generation for chip use
    4.Produce variable pulse signal,the control-related circuit (PWM dimming,speed)
    Module Description:
    Frequency is divided into three ranges:
    1.XXX (no decimal point):the smallest unit is 1Hz,the range 1Hz-999Hz
    2.XX.X (decimal point in ten):The minimum unit is 0.1Khz; the range of 0.1KHz-99.9KHz
    3.X.X.X.(there are three decimal point): the smallest unit is 1Khz; the range 1KHz-150KHz
    Frequency Display Example:
    1."100" indicates that the PWM output pulse of 100Hz
    2."54.1" indicates that the PWM output pulse of 54.1KHz
    3."1.2.4." Indicates that the PWM pulse output 124KHz
    4.Duty Cycle in the range:0 to 100
    5.Three frequencies duty cycle is the same,all the parameters non-volatile
    Serial Port Control:
    1.Baud rate:9600 bps
    2.Data bits:8
    3.Stop bits:1
    4.Parity bit:none
    5.Flow control:none
    6.Set The PWM Frequency
      1)"S1FXXXT":setting PWM1 frequency of XXX HZ (001 ~ 999)
      2)"S1FXX.XT":set the frequency of PWM1 XX.X KHZ (00.1 ~ 99.9)
      3)"S1F:X.X.X.T":setting PWM1 frequency of XXX KHZ (0.0.1 ~ 1.5.0..)
      7)'D':Duty Cycle
      8)'T'is the end flag
    7.Set The PWM Duty Cycle
      1)"S1DXXXT":setting PWM1 duty cycle XXX;(001-100)
      2)"S2DXXXT":set PWM2 duty cycle XXX;(001-100)
      3)Setting Successful Return:DOWN
      4)Setting Failback:FALL
