3 Way Digital PWM Signal Generator Pulse Frequency Duty Cycle 1HZ~150KHZ Adjustable Square wave XY-LPWM3

3 Way Digital Signal Generator PWM Pulse Frequency Duty Cycle 1HZ~150KHZ Adjustable Square wave     1 .Module Features:

1.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
2. LCD can display frequency and duty datio,Easy to oprate;
3.Wide frequency range, high precision;
4.Support Serial operation   2.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: XXX(No decimal point): 1HZ Stepping Unit, Range: 1Hz~999Hz;
X.XX(The decimal is in the hundreds place):0.01KHZ Stepping Unit, Range: 1.00Khz~9.99Khz;
X.XX(The decimal is in the tens place):0.1KHZ Stepping Unit, Range: 10.0Khz~99.9Khz;
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.   3.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.   4.Module Parameters:   1.Operating voltage:3.3~30V;
2. Frequency range:1Hz~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°C.     5.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).
5,UART Serial command

Baud rate:9600 bps Data length:8
Stop bits :1
Check digit:none
Flow control:none 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) 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%   6.Read Setup parameters
