An important question missed here is does this remember the last known setting after it is powered off and back on?
Would be excellent for switching power supply experiments.
See how frequency and duty cycle effect the output voltage and efficiency of say a boost converter.
Would need a gate driver added as it cannot drive mosfets directly with that low mA rating.
Hi, I have a bike that I want to simulate a digital signal from a abs sensor to the abs unit, it is 1.5volts input. My question is, works with 1.5volts input?
Why i cant run it? Isolated components works well but when i make circuite with this components my dc motor not working... why?
Thank you for the nice and detailed explanation!
Super handy little module I may have to pick one up

Hello. What is the frequency number of tunnel and closed underground room?? in Hz or kHz
Hello, I have this generator but the output is always OFF on the display, how to enable the output to be PWM signal?
Great review. What do you call the power supply box to power the meter. I would rather have the flexibility to plug into an outlet rather than fiddle with a battery. Thanks.
Could this drive a piezo element? If so, would increasing the voltage simply make the piezo louder?
Handy little module to have around! And at a nice price including the case...
Thank you for a professional demonstration :-)
Thanks for the video. I have a question about the unit. I can not seem to get the output the same voltage as the input. I can only get a oscillation of around 1.5V irrespective of the input voltage. Is my unit faulty or am I doing something wrong. Thanks Joe
I can’t remember the full specifications but there may be a little less output than input voltage because it’s being switched by a transistor that will have some loss across it but if it’s only 1.5 V no matter what, then it sounds like something strange is happening.
Hi couod you please tell me how to connect this to my welder it has a 78v 200amp output and I want to use this pwm as a pulsing add on for my tig welding
HI There, Very good explanation and testing, thank you.
can this be set as positive offset frequency?
Nice device. Thanks for the review.
Do you know what wire this taps into on an alternator for voltage control?
Interesing! Informative! Bargain!
Voltage too high and current too low to feed a PULSE mode 500-1000mW (610nm-633nm) laser diode at 2-20Hz! (laser diodes are generally ~2-3V at up to 2A) any ideas appreciated!
Can i control the intensity of halogen lamp with this pwm
Very helpful item
Really thank you for interesting information 😎
Nice video, thanks! Can a signal generator perform the same duties as this PWM device?
if it’s a respectable signal generator and not some $20 kit, it should be able to vary the duty cycle and frequency on at least the square wave output as well as adjusting the voltage and offset so it doesn’t necessarily just go from zero to some positive voltage so generally yes, and even better if it has a USB interface where you can set it up for automatic triggering and testing.
I usually use the one in this video th-cam.com/video/pOSEm8VeXAU/w-d-xo.html
@@GadgetReboot Thanks for the info!
So thats how they make chasing leds nice 👍
what could i do to increase the output current?
Great device . would you pls get me device which can generate frequency upto 500 kilo hetrz
Pueden hacer la prueba con tonos y parlantes por favor
can it be used for achieving ac output?
The output swings between the + and GND supply
Does anyone have any idea how to connect two of these units in tandem, so that the first in the row acts as a timer for the second?.Thanks!.
What would be the intended behaviour of the system, does the first one basically enable the second one so when the first one is high, the second one generates its clocks and when the first one is low the second one stays disabled or something?
The only way I can think of to control them is either using the Uart to send commands, or have two of them free running and then some other little digital logic circuit to gate them and enable them as needed.
@@GadgetReboot ,
I will try to explain better.I have two of these modules available.I have programmed the first one, in 'PULSE' mode, so as to give me an 'ON' time of half a second,and an 'OFF' time of half a second. I connected this module to the 'STOP' input port, that is behind the pcb of the second module. This last module, I programmed it,in 'PWM' mode, at a frequency of 100 Hz, 50% duty cycle , and I connected a small speaker to it;to have an auditory test of the correct functioning. The results?. Everything works except for the pulse times of the first module. By ear, the times are doubled. From half a second, I got a full second,as timing. Please give me the solution to this riddle.Thanks.
@@Jeanpaul465 that sounds like a different module than I have so I looked at IC Station and it sounds like this module ZK-PP1K so looking at the way they wired up the enable on the back it looks like it’s either left open or connected to ground so I wonder if one problem is it does not want to be directly driven high by the pulse generator, so I wonder how it would work if you connected the pulse to a transistor, so if you put the pulse on the base of an NPN through a 1K resistor or something, emitter to ground, collector to the appropriate enable pin on the second unit, then it will either be floating or connected to ground like they show with the push button.
Otherwise how does it look if you separate the two units, if you manually ground the enable can you make the PWM start and stop as expected?
And if you put a scope or a multi meter on the pulse output, does it look like it goes high and low at the right timing?
Another reason to use the transistor to just connect the enable to ground but not any logic high, I wonder if that enable input is only 3.3 V tolerant because on my unit the UART is only 3.3 V so if I am powering the entire thing from 5 V I need a level translator to talk to those types of ports.
If you really want to ajust your duty cycle just eat at Taco Bell, LMAO All jokes aside nice product and good revue, Would go good on my bench!
Taco Bell would have the adverse impact of shortening the lifespan though. I like this little PWM generator and I think I want to get some similar little tools like that soon.
I got that remote connected to alternator in car so i can go to 15.5 volt to charge my lto batteries
Have the ali version. No instructions 😂
