STM32 PCB Design - Complete Walkthrough - Altium Designer & JLCPCB - Phil's Lab #41

very useful gadget

thank you Phil your videos are very helpful

Great job Phil ! I think the culprit for Altium not allowing to paste the part number is the space character at the end of the part number. Obviously it's a bug

Nice video, well done, thanks for sharing :)

batery of condenser''s, why , when from ,

Do we always need IMU (in this case MPU-6050) with STM32 or not? In what cases do we need it?

Hello, thank you very much for your good tutorial, how can I access the libraries?! Can you share them or email me?

In the PCB stack, you entered the value for Dk but not Df. Why is that?

If i cannot aford altium licence can i use circuit maker to do this? are these software alike?

Why do you need two ground planes. Why not only 1? I think that you don't even use L3(GND) plane since all the ground connections from L1 go to L2(GND).

Talking about ferrite bead, isn't it that this component shall create large sharp peaks in the PDN impedance and thus is bad?

Why did you not seperate VREF+ (Called VDDA in KiCAD STM32 Video) to 2 different 3.3 Voltages, one Analog and one your common +3.3V?

Edit: I wonder if he ended up using a different STM32 board, and that is probably why.

Thanks so much for making all these tutorial videos that shows entire process from start to finish with the rationale for the decisions made. I have a couple questions about impedance controlled traces between your designs in the videos and in the GitHub repositories.

In the video you set up the USB trace widths for the JLC7628 stackup (0.26mm), but the gerbers in the GitHub appear to show them at 0.1532mm. Did you end up changing to producing this in the JLC3313 stackup after the video was finished? I'd like to get some boards produced and just wanted to make sure I have this correct.

I see a similar-ish thing with the previous LIttleBrain board, where in the GitHub history the USB trace widths were originally 0.2611 mm, but when you did a revision to remove the USBLC6-2SC6, the trace widths went to 0.2mm. Was that just a simplification and this level of detail doesn't matter at such short trace lengths?

Thanks again for all the fantastic videos.

Outstanding. Thanks.

Hello, good content and easy explanation, here you have provision of 4 layers, yet you used only top and bottom layer, you could have gone for just two layers

is double sided pcb where bottom is digital and top is analog good idea? 4 layers, top 12v, bottom 5v and 3.3v and middle layers both ground?

where can i get that tc2030 debug header file for altium?
do i need to make it myself?

Great video Phil! I didn't really understand where can this PCB design be used in. Can someone explain it to me? Thanks

Why connect the USB data lines if you're going to program using SWD?

Why 2 ground layers?

Excellent !!! Thanks a Lot

can you create your own STEP files in altium?

Can this board be directly programmed via USB?

I can't make a difference between first generated gerber file and second generated gerber file, stiching vias are not shown in internal (GND) layers???

So, how many times have you closed the video because of ctrl+w?

Phil is awesome engineer and kick as_ guitar free solo :)

Are we sure that MCU has an internal crystal, not a lower precision RLC oscillator?

If someone is wondering why sometimes you can't copy and paste MPN (Manufacturer Part Number) from JLCPCB altium, it because of the while spaces at the beginning of the MPN. You need to remove the white/blank spaces first. I am not sure this is clear but yeah, you need to remove the white space at the beginning.

Thanks for the video. Just a quick question, I don't have GND vias placed under the chip on my footprint taken from STM website. Should I place them manually?

What about GND plane under the crystal oscillator? Great video by the way!

Great video.
Question. I'm replacing my ebike motor pcb. My original pcb has 5V GND SP H1 H2 and H3 components that's I'm familiar with and know how to connect.

My replacement pcb has these connections PLUS a "K" (relay?) and "-" beside it.

What is relay used for? Does K mean relay? And, since "K" is not a component on my original pcb does that mean this pcb will not work unless connected to some type relay?

Tried looking online/Google. No luck. Need some help. Hope u can.

How about the availability of the stm chips nowadays? I’m using ESP32 now.

Great video. Your videos about pcb design assist to us. I have a question about stack up section. When you adjust the layers of the pcb, you selected in the power and ground layer as signal instead of plane. In this video you mentioned that this choices avoid creating a negative gerber. Does this choices make sense? The senior employees who work in our company always prefer the plane. I'm confused as a junior hardware engineer. Regards.

Brilliant stuff Phil, learnt so much from your videos. Thank you.

This is one of the great AD tutorial on the YT. I could not found the library (symbol and footprint) in github page, could you pls tell us how to download it? Thank you a lot.

Thanks for your videos Phil

Thanks for great video. Where can I find the altium footprint library you used in this tutorial?

awesome video! I think you forgot to put your altium symbol and footprint library in the description. Can you please add them to one of your repos?

I can not find the library he mentioned in his github. Anyone know where can in find it?

Very very good

so good show, new friend

Do you use diptrace? would love a tutorial with that!

Can you post a link to your library as you mentioned in the video. Thanks. Great video btw, better than anything else that is out there.

This is great intro to Altium. Thank you so much for your effort

Can you help me find Footprint-Lib-PhilsLabPcbLib and Schematic... for me to be able to follow along

Isn't each individual VDD pin supposed to be connected to the ground through a capacitor? Then how come we put 5 parallel caps and connect all vdd pins to each other and then connect them between + and -? Doesn't the behaviour change?

In other words instead of connecting each pin to a 100 pf cap we are connecting all of them to an equivalent 500 pf cap(parallel caps add up)

thanks, helpful video
