Review of ZK-PP2K 8A PWM 4.5V to 30V Motor Driver | Robojax

[@omarhamza9717]

you are the only one eplane zk-pp2k very will >>>> thanks man

[@chbonnici]

Great first class demo, thank you.

[@royalarch3539]

Mindboggling post, very interesting. Keep posting.

[@str0g]

It would be great if you could do a followup on elaborating what the frequency actually does since you have the duty cycle which defines the on off portion of a cycle.

[@robojax]

I have done so many of those types of explanation. it seems the world does not care to learn. they just want to get it and use it. I've spent so much time creating the figures but, most viewers don't care. if user don't appreciate it, I will not make contents. As of now this video have been viewed about 300 times and and yet 18 people have thumb up the video. Subscribers who are getting notified and watch do not not care and do not understand a simple thumb up, will bring this video higher in the search result. So my contents are driven by user.

[@str0g]

@@robojax sorry to read that. I find ur explaining not tiring and keeps up my attention. I'm new to ur channel, so if u did one about duty cycles then maybe it would be good to mention that you did a video covering all knowledge required as a base to fully understand this video. This way you would entice your viewers to explore ur channel.

Good demonstration. Thank you.

Thanks...Great explanation on how this works. Keep up the good work!

I am planning to use this as a driver to an ignition coil. I burned one unit already. I think the mosfet inside cannot take the backEMF. I will try to put a snubber diode accross my primary to combat this, but I think I might have to get a beefier mosfet and the ZK-PP1 which does not have an internal mosfet.

[@UnrealTransformer]

The internal switching transistor is the type "RU3560L" and the unit has an snubber diode added to the circuit already.

[@eddysmit]

Thank you for this very good video! Maybe one question. How does it react after disconnecting the power and connecting again. Does it remember the settings and the on or off state?

[@robojax]

Yes it does

[@eddysmit]

Thanks a lot

[@minamatta6135]

Thank you sir ❤️❤️❤️ nice video ☺️

[@EarthquakeCL]

Ey my friend, great video. I was looking for a thing to create a cleaner inyector, someone recomended me the pwm generator of 1 way (the little brother of zk-pp2k) but looking at your video I will need the pulse generator or thats what I understand. With this I can config the inyector to open every 0.3s to make a fast tick tick tick for the cleaning process, correct? I was trying to know if I can connect 4 inyector at once on this device or maybe better one per one?

[@ДенисРадионов-с8ц]

Thank you very cool!

[@taom6708]

Hi, please can you describe how to attach a heatsink to the mosfet? Can i fix one on top or is it necessary to remove the mosfet? Thank you!

[@robojax]

Hi, yes just attach it and make sure it is in contact with mosfet . You must put heat transfer command between heat sink and the surface of mosfet

[@TMRu22311]

@@robojax Would a peel and stick type heatsink for like a Raspberry Pi work okay?

[@vivendonositio9958]

Gostei muito da explicação 👏👏👏👏

[@Electronics61]

Great video

[@TMRu22311]

This is the best video I have found to explain these devices, Thank you. I was wondering, is this for brushless motors only or can you use brushed motors as well? Also, what is the recommended input voltage for this device? I know you said between 4v-30v, but would a higher voltage have any benefits? Thank you RJ :D

[@robojax]

Hi, Glad you found it useful. No you can't go higher. the module will die.

[@TMRu22311]

@@robojax I understand input voltage cannot exceed 35v, but would you benefit running it at 24v as opposed to say 5v or does this not matter?

[@iliebologa662]

Thank you for nice video!

[@gerard9114]

I want to control a single LED of 1.8V. Is it possible to lower the output voltage? Maybe with a buck converter behind the PWM?

[@hydrocarbon82]

Given the connection diagram, it pulses the ground (OUT -) so you should be able to. You'd connect the LED ground to the unit, then 1.8v to only the LED. The ZK-PP2K would still need it's own >3.3v power to V+. I'll be trying this when I get mine since I'll be controlling a solenoid that's powered from a different location, hopefully letting me run 1 wire thru the firewall instead of 2.

[@Ron-sk8wo]

Hi great video as always. You mentioned a a heat sink on top of the mosfet any idea what to use

[@robojax]

Hi, you can use on of these amzn.to/3IYIMwJ

Is it possible to drive a tesla coil with it?

[@dcfelectronica4030]

Hola Ahmad, soy de Argentina. Te pediría que subas un video como éste del ZK-PP4K es un módulo bastante reciente. Le mando un saludo desde lejos.

[@robojax]

Hola DCF Electronics, bienvenido a Robojax. si alguien me paga por revisarlo seguro que lo haré.

[@Go4BrokeOffroad]

Solid test

[@steveschweer]

I connected this unit to 16vdc. All controls work as specified. BUT… the output remains at 16vdc at all times! It does not turn on or off with the “out” control. No square wave is shown on my oscilloscope. I thought that the unit was bad, but a second unit does exactly the same thing. Any idea what’s wrong? Any help would be greatly appreciated. Steve

[@gustavobernal5377]

Good day @Robojax, I´m new to your channel, and this video lead me to it, i found your explanation very easy to understand and i thank you for uploading this video, i have just 1 question, the output signal´s duty is control by this driver, Im trying to control a laser for my cnc, it has 3 pins 12v+, 12v- and PMW, do you know if i can use this output for the pwm in the laser? if you made a video about that please point me in the right direction. Thanks you so much!

[@robojax]

Good day, no this can't be used. Yours is dual power which makes is 12V+12V=24V. Even if you connect 24V it won't work as you need GND or (-) pin.

[@gustavobernal5377]

Does this module have an internal flyback diode?

Yea it does.

How can i use this with 4pin brushless PC fan

[@zedixquatrevingtun4253]

Hello, what is the ouptut frequency in pulse mod ,please?

[@robojax]

If there was such information I should have explained it in the video. So watch fully. I don’t remember

[@kipsalviv5742]

Thank you

[@chbonnici]

Is it possible to drive an ignition coil with 12 Volts supply?

[@robojax]

this is to control a load that needs PWM like motor or LED. I am not sure it works with igniation coil.

[@e.quasselbude]

Does it save settings after power off

[@robojax]

Of course it does.
