Hey Kyle, thanks a lot for this video. My first job after graduating will be as an electronics engineer early next year, it's helpful to see how an experienced individual goes through the process. I hope that in your future videos you continue with this style: discussing your design process and techniques. There are plenty of resources on kicad and other CAD, no point in getting lost in the noise. I think what you did with this video is a healthy niche.

14:15 after placing your first global label hit INSERT key couple times, it will put new label with incremented value

[@MicroTypeEngineering]

That's immensely timesaving, thank you!

[@luise.ardila9200]

wow, how didn't I know this before, huge thanks!

[@10e999]

I really like this format. It really underline the design choice you're making while designing the board. I hope you will continue this series with an other project !

[@simonndungu1196]

I love this guy, he is hitting it right and hard enough, Thanks

Great videos for all KiCad users to become more professional engineers!

[@easyamp123]

Welcome to designing automotive equipment. When you've only got 14 volts you got to get the power from somewhere, amps. Keep up the work, good stuff

[@kentvandervelden]

Hugely helpful to someone learning KiCad and best practices. Thank you!

[@blacklion79]

Thank you, it is exactly what I need for my next project (not a LED driver, though)!

[@davidcain3752]

Wow, thank you so much for these practical looks at electronics and circuit design! Feel excited to use mosfets more often

[@idreesbronamed7501]

What a video! I learned a lot being a rookie. Great stuff dude

[@seckinseckin3919]

you can also open subtitles.. Thanx for great drawing videos.. İm an engineer too. Salute from Turkiye ..

[@DanielPianoful]

Subscribed over the promise of a future KiCad 5 tutorial :)

[@MicroTypeEngineering]

What specifically would you like to see? I know there are several tutorials out there on Kicad already.

[@DanielPianoful]

I imagine a "lets build a thing" per video kind of approach to be both entertaining and informative, the equivalent with kicad of what the "logos by nick" channels does with inkscape, that would be amazing!

[@MicroTypeEngineering]

@@DanielPianoful Gotcha. Since these more complex boards take too long to do a real-time tutorial, would you rather see simpler boards, commentated live, or time-lapsed explanations like this current one? Or, a complex board that has real-time commentary, but spread out over many videos?

[@DanielPianoful]

@@MicroTypeEngineering mmhh the first and third options sound the best, maybe start with simple/singles video boards and then progress to more advanced boards. Try what's the most fun for you to do, will be watching and sharing anything you publish :)

[@andymouse]

@@MicroTypeEngineering Hi...long and detailed please specifically about using KICAD.

[@Electheo]

Nice video! Really understandable way of explaining everything that you’re doing. Keep it up :)

[@dylandailey3191]

Why do you start with power supply design first? My mentor did this as well, but my argument is that you should design power last so that you can analyze the rest of the circuit to determine your min and max power supply ratings. There have been a number of times where scope creep has lead to me redesigning a power supply because new components burst the power budget.

[@MicroTypeEngineering]

Valid point. I do it because I do the power portion of the PCB first as well, and just keep it consistent. But I have all components picked out and fully spec'd before I start the schematic to avoid your concern. But overall, there isn't any real reason to start with power first, just personal preference.

[@suhaimiannuar6008]

perfect yet easy to understand. wonderful

[@humbleguy9908]

Thank you for the concise explanations. Just a small detail which I may misunderstand: The max resistance of 15.2 mOhm corresponds to a VGS of about 4.5 Vin the graph. Would that not allow you to switch it using 5V-logics?

[@jamesslade2862]

@MicroType Engineering Not that it matters too much for this build, but if you stagger stitching vias, instead of uniform, you have a lower chance of resontating signals that cause EMC issues

[@DustinWatts]

Thanks for your video! Good information on MOSFET selection.

[@drakonzebra]

What are the advantages of using a specialized MOSFET driver over an another, small, MOSFET?

[@MicroTypeEngineering]

Mainly ease of design. A small FET will work equally as well, and is cheaper.

[@AlessioSangalli]

Interesting you use the Microchip gate driver. I was tempted to use it in the past but - you're probably going to laugh - it felt wrong to get an analog power part from a company most famous for microcontrollers that I used since the 90s. I understand that at least for low frequency application these work good. I looked up Microchip's history and it seems they acquired several semiconductor companies so they have a diverse portfolio. They even own not one but several fabs all across the US, mind-blowing

[@metamud8686]

21:28 "LCD" or "LC Display", but not "LCD Display" as that would be a "Liquid Crystal Display Display" which I'm sure it is not. 🙂

[@jacobwiqvist1760]

What is the best N-Channel MOSFET for driving 10A 5-60V PWM with an arduino?

[@voytechj]

8:10 you said that this IC can be used as high-side driver but as far I know it does not have charge pump inside like for example MIC5018. I never designed anything with drivers so I may be wrong.

[@joshua43214]

Thank you. Very useful video.

[@cveja69]

Why don't you have resistors on leds, in mosfet drain? Ty in advance.

[@christopherrod7]

Hey there man, I'm currently an EE looking to go into the design field. But as I watch videos and learn on my own, I feel like it's something I need practice with to actually understand it. I do however understand the fundamentals and how each component works, is just the bigger picture that I Don't see right away. Is this normal for an EE starting in the design field? Or am I missing something here? Any advice would help man. Great video as well:). Definitely subbed

[@MicroTypeEngineering]

Well, I can't directly speak to this - my major was mechanical engineering ironically - but, yeah I think that is pretty common. For me at least, it was a matter of learning a bunch of circuit building "blocks" one by one. I soon learned enough of these blocks that when I needed to build something from scratch, I could just piece them together until I had what I needed.

[@aliebrahimian4445]

Does kicad have Teardrop function ?

[@MicroTypeEngineering]

I believe there is in a plugin

[@christopherbrown7419]

Subscribed! Looking forward to the next videos.

[@demi3431]

Hey there! can you tell us the lcd screen that you use for these projects?

[@MicroTypeEngineering]

4DSystems diablo based intelligent touch screen.

[@vredzhepov]

Hi there, Kyle. This circuit doesn't contain polarity protection unit. What do you think about that?

[@MicroTypeEngineering]

Yeah, definitely would be a good addition to have! Didn't want to detract from the main circuit design itself, but I may do a video on that topic actually. Any time a user can mess up polarity, it's a good idea to have protection.

[@blacklion79]

KiCAD is very inconvenient when you need several equivalent blocks :-( Changing each block (like output channel in this project) individually is very cumbersome :-(

[@MicroTypeEngineering]

Yes, you are right. Hoping KiCad 6 helps this
