XY-WPWM Pulse Frequency Duty Cycle Adjustable Module Square Wave Rectangular Wave Signal Generator
Module Highlights:
1.LCD display frequency and duty cycle, very clear, PWM output can be set to the frequency and duty cycle;
2. Wide frequency range, high precision;
3. Serial communication, TTL level
First, the module description
PWM output, you can set the frequency, duty cycle;
Frequency is divided into four ranges, automatic switching:
1. XXX (no decimal point): the smallest unit is 1Hz, the value range of 1Hz ~ 999Hz;
2. X.XX (decimal point in the hundred) the smallest unit is 0.01Khz, the range of 1.00Khz ~ 9.99Khz;
3. XX.X (decimal point in ten): the smallest unit is 0.1Khz; value range of 10.0KHz ~ 99.9KHz
4. X.X.X (decimal point in ten and hundred): the smallest unit is 1Khz; value range 1KHz ~ 150KHz
frequency display: 100 indicates PWM output 100Hz pulse;
1.01 indicates PWM output 1.01K pulse;
54.1 indicates that the PWM output has a pulse of 54.1 kHz;
1.2.4 indicates that the PWM output is 124 kHz pulse;
Duty cycle range: 0 ~ 100%;
All set parameters, power-down automatically saved.
Second, the parameter settings
The module has four independent keys, used to set the frequency and duty cycle, support touch (increase or decrease a unit) and long press (fast increase or decrease), set the parameters automatically save, power down Not lost.
Third, the module parameters:
1. Working voltage: 3.3 ~ 30V;
2. Frequency range: 1Hz ~ 150KHz;
3. Frequency accuracy: the accuracy in each range is about 2%;
4. Signal load capacity: the output current can be about 5 ~ 30ma;
5. Output amplitude: PWM amplitude equal to the supply voltage;
6. Ambient temperature: -20 ~ +70 ℃.
Fourth, the scope of application:
1. Used as a square wave signal generator, generate square wave signal for experimental development and use;
2. Used to generate a square wave signal that controls the motor driver;
3. generate adjustable pulse for MCU use;
4. generate adjustable pulse, control the relevant circuit (PWM dimming speed and other applications).
5, serial control (single-chip TTL level communication)
Communication standard:
9600 bps Data bits: 8
Stop bit: 1
Check digit: none
Flow control: none
1, set the frequency of the PWM
"F101": Set the frequency to 101 HZ (001 to 999)
"F1.05": set the frequency of 1.05 KHZ (1.00 ~ 9.99)
"F10.5": Set the frequency to 10.5KHZ (10.0 ~ 99.9)
"F1.0.5": set the frequency of 105KHZ (1.0.0 ~ 1.5.0)
2, set the PWM duty cycle
"DXXX": set the PWM duty cycle to XXX; (001 ~ 100)
Such as D050, set the PWM duty cycle is 50%
3, read the set parameters
Send a "read" string to read the set parameters.
Set successfully return: DOWN;
Setup failed to return: FALL.

Women's Sizing & Fit Guide
Please be aware that most of our clothing is Juniors' sizing, which runs smaller than regular US / European Women sizing. Refer to the measurements chart for each individual product to determine the best size for you. Product specific size chart and information can be found in product description or in product picture gallery.
Our team does it's best to include accurate size details and measurement of each item in the product descriptions. If you have questions regarding sizing or any other information on a specific item, please email us at support@mrslm.com for specific details.
Find the best size
When comparing your measurements to those listed on the site, make sure to check if the fabric is stretchy or not. If it is, it can stretch an inch or more.
- Bust: Wrap the measuring tape loosely around the fullest part of your bust to ensure a comfortable fit.
- Waist: Measure the narrowest part of your natural waist, holding the measuring tape loose enough to fit comfortably.
- Hips: Drape the measuring tape around the widest part of your hips, resting the tape comfortably against your body.
- Length: For tops and dresses, measure from the top of your shoulder to the hem. For strapless dresses, measure from the highest part of the neckline to the hem. For pants and skirts, measure from the top of the waist to the hem.
- Sleeve: With your arm outstretched, measure from the base of your neck to the end of the sleeve hem to determine where the sleeve length will fall on you.
