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°
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.
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.
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).
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
Size:5.5x3.8cm/2.17x1.50inch
Note:
Please allow 1-3mm error due to manual measurement. pls make sure you do not mind before you bid
