Signal Generator Module Adjustable PWM Pulse Frequency Duty Cycle Square Wave GL
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 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.
Specifics:
Condition: 100% Brand New

This axle bearing and seal kit made my Bobcat smooth and quiet again. Quality parts, easy install, and no more leaks. Great value for the fix.
These nozzles are perfect for my diesel equipment. Installation was straightforward and they've fixed my fuel spray issues. Great, reliable performance.
This little converter works perfectly. It's silent, waterproof, and does exactly what I need. I mounted it permanently this time, but it’s versatile enough to move around if needed. Great value.
This portable gas leak detector is a must-have for any technician. It's incredibly sensitive and reliable, giving me full confidence when checking gas lines after installations. Customers really appreciate the extra safety check. Excellent tool!
This automatic flow switch works perfectly with my water pump. It turns on the moment I open the tap and shuts off instantly when closed. Easy to install and very reliable so far. Great product!
It fixed 2 problems--AC going off and on (breen light too). Ac was always pulling outside air in--now I can switch to recirculation. My husband had no trouble with the install even tho he is disabled.
GREAT
Great fit overall.
Good communication
Great product. Delivered on time and as explained. I screwed up the order and the bent over backwards to help me. Great company.
Great product, fits perfectly, and of course looks so pretty, it gives a nice beautiful new look to my truck, also I contact costumer service and they help me pretty fast, totally recommend this company
Looks great perfect fit
Finallly, they solve the problem. Good service
😊
Everything fit perfectly 👌
Got it in 8 days
Good looking will install it tomorrow
Grill fits well
Removing the OEM seals were harder than I expected. However, installing these new ones were WAY easier than I expected! The new clips lined up perfectly, even though I didn't hear all of the clicks. They are firmly in place and look great.
The quality and fitment was on par with OEM. It was an easy install with no issues.
