    Features:

    • Support Serial operation

    • Wide frequency range,high precision

    • LCD can display frequency and duty datio,Easy to oprate

    • Output of three-channel PWM at the same time, Adjustable frequency,3-channel frequency output consistent,duty ratio can be independently adjusted,suitable for most occasions

    Parameters:

    • Operating voltage: 3.3~30V;

    • Frequency range: 1Hz~150KHz;

    • Frequency accuracy: In each range of accuracy is about 2%

    • Signal load capacity: Output current can be around 5~30ma

    • Output amplitude: PWM amplitude and supply voltage equal 

    • Ambient temperature: -20~+70°

    Frequency is divided into four areas,automatic switching:

    • 1.XXX(No decimal point): 1HZ Stepping Unit,Range:1Hz~999Hz;

    • 2.X.XX(The decimal is in the hundreds place):0.01KHZ Stepping Unit,Range: 1.00Khz~9.99Khz;

    • 3.X.XX(The decimal is in the tens place):0.1KHZ Stepping Unit,Range: 10.0Khz~99.9Khz;

    • 4.X.X.X(The decimal is in the ones place):1KHZ Stepping Unit,Range: 1Khz~150Khz;

    • e.g. ,frequency display:100 represent the pulse of 100Hz ;

    • 1.01 represent the pulse of 1.01KHz; 

    • 54.1 represent the pulse of 54.1KHz

    • 1.2.4 represent the pulse of 124Hz

    Application:

    • Used as square wave signal generator to generate square wave signal for experiment development and use

    • Used to generate a square wave signal to control the motor driver;

    • Generating adjustable pulses for MCU use;

    • Generate adjustable pulse, control related circuit (PWM dimming speed and other applications).

    UART Serial command:

    • Baud rate: 9600 bps Data length:8

    • Stop bits:1

    • Check digit: none

    • Flow control: none

    1.set the frequency of the PWM 

    • "F101": Set frequency of 101 HZ (001~999)

    • "F1.05": Set frequency of 1.05 KHZ(1.00~9.99)

    • "F10.5": Set frequency of 10.5KHZ(10.0~99.9)

    • "F1.0.5":Set frequency of 105KHZ(1.0.0~1.5.0)

    2.set the duty ratio of PWM

    • "DX:YYY": Set PWM duty ratio x: (1~3) PWM serial number,YYY: (000~100) duty ratio;

    • For example d1:050,set 1th PWM duty ratio to 50%

    • 3.Read Setup parameters

    • Send a "read" string to read the parameters of the setting.

    • Message format:F156,D1:052,D2:059,D3:058,

    • Set successful return:DOWN

    • Set failed to return:FALL
