ماژول PWM SIGNAL GENERATOR 3 CHANNEL:

3 Channel PWM Board Module Pulse Frequency Duty Cycle Adjustable Module Signal Generator 1Hz-150Khz with LCD Display
Module Features:
1.Output of three-channel PWM at the same time, Adjustable frequency, 3-channel frequency output consistent, duty ratio can be adjusted independently, 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
Module description
Three-channel PWM is implemented, wide frequency response and 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 100 Hz;
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 duty factor: 0 ~ 100%, 100% is represented by A0%.
All parameters set up can be saved automatically in case of power failure.
Parameter settings
Module has 8 independent keys, used to control the frequency and duty ratio, support short press (increase or one unit) and long press (rapid increase or decrease), very simple, 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 different road duty ratio scan.

Module Parameters:
1.Operating voltage:3.3~30V;
2. frequency range: 1Hz ~ 150KHz;
3. Frequency Accuracy: In any range of accuracy is about 2%
4. Signal load capacity: output current can be around 5~30ma
5. Output amplitude: PWM amplitude and power supply voltage equal
6. Ambient temperature: -20 ~ + 70
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 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. the frequency of the PWM
“F101”: Set frequency of 101HZ (001~999)
“F1.05”: Set frequency from 1.05KHZ (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 not return: FALL
