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:
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.
Applications:
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).
Package included:
2* 3 Channel PWM Pulse Generator Module Adjustable Frequency

Works well. Not sure how accurate it is but I have full adjustability for what I need.

I think I only cursed once setting this up to drive a pulsing electromagnetic wave. It's an interesting device. If you have an oscilloscope, grab a pair of these. It's a good use of an evening.

For what I'm doing this is great. Cost is outstanding and does a very good job.

Seems to work OK. You adjust the frequency for all three channels. The channels all rise together and the falling edge is adjustable. Not what I needed, but if this meets your needs it works fine. There are no posts, so you'll need to solder wires or use your own posts. Very easy to use. It looks like there are programming pins but no information on the microcontroller, may be under the LCD.

PROs:This Generator has 3 channels. Each channel has the same frequency and every channel has own PWM value.CONs:1) The phase between channels is RANDOM. It's not 0, it's just random if you change PWM of channels or change the frequency, it's somewhat the same, but you can't say exactly the value. I wish it would be 0 fro all channels, but it's not. If you use fixed generator or don't need channel sync - it's not a problem.2) The generator has UART, but there is no info how to use it.3) The actual width of PWM pulse depends on the frequency, not dramatically, probably due to the integer math inside the module.

Product is different from what I expected -- but that's on me, because I didn't read close enough and understand the description. This 3-channel PWM signal generator can be adjusted to provide different duty cycles on each channel, but the frequency will be the same on all three channels.Note to HiLetgo: If you built and sold a similar product that allowed setting different frequencies for each channel (but the same duty cycle on all three), I think you would sell millions of them.That said, this device worked exactly as described (once I re-read and understood the specifications). Considering all the controls and the backlit LDC display, it is an amazing value for the money.

Frequency is not adjustable on each Chanel. Duty cycle on 3 Chanelle of the set freq.
