Характеристики


PWM pulse frequency and duty cycle adjustable module square wave rectangular wave signal generator signal XY-LPWM


 


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

 

Specifications:

1.Operating voltage3.3~30V;

2. Frequency range1Hz~150KHz;

3. Frequency accuracy:In each range of accuracy is about 2%

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

5. Output amplitude: PWM amplitude and supply voltage equal 

6. Ambient temperature:-20~+70°

 

First.Module description

Three-channel PWM  is outputted,wide frequency range and the duty ratio can be adjusted independently

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

The value range of dutyfactor: 0~100%,100% is represented by A0%.

All parameters setted up can be automatically saved in case of power cut.

 

Second.Parameter settings

Module has 8 independent keys,used to set the frequency and duty ratio,support short press (increase or decrease a unit) and long press (fast increase or decrease),very simple,set the parameters automatically save,power loss.

3-Way duty ratio button can be pressed at the same time,real-time adjustment, liquid crystal display is the last pressed button duty ratio,real-time is very strong,can be used as a simple several road duty ratio scan.

 

Third.Scope of application:

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

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

3.Generating adjustable pulses for MCU use;

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

 

Forth.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
