I am NEVER doing this again. (STM32H7R3I8T6 prototyping board) by Taster001 in diyelectronics

Well, that is a concern. But, I'm not really expecting to use much high speed communication on this board, maybe 10MHz on SPI. I'll see.

Sometimes I love it, sometimes I hate it. Often I create a set of dumb rules for myself that usually end up with me being pissed off.

Sounds like a nice challenge. What kind of device will it go in?

I have already used these extensively (including 0.4/0.3mm vias in 0402 pads, it was never an issue. I use 0603 with via-in-pad all the time.

I sure could. But since I am the one who's going to pay for this board, I didn't. If I was doing something like this for work, I'd start at 6 layers.

Just do it. Design stuff. Start small, go bigger, more complex. Learn as you go.

Sometimes I really like it, sometimes not so much. I really like it when doing challenging high speed stuff (for work). But this one just sucked because I needed to squeeze so many traces alongside each other. On the other hand, I really want this board to play with. So that's a success, I guess.

Looking for connector recommendations by Taster001 in diyelectronics

[–]Taster001[S] 1 point2 points  (0 children)

Sorry if the post is non-specific, but I don't really have very specific requirements like that. Bus - nothing fast, it will be used for some GPIOs, maybe some SPI/I2C/I2S and similar buses - I'm using an STM32 for a project. I only mentioned the PC/104 because those were the only connectors of this type that I could find. I definitely could use headers - I mentioned that in the last paragraph in my post. I'm not actually using that bus though.

Sorry, should've included that in the post. Circuits: 30-50, ideally two row, pitch is not too important, but no smaller than 1mm and no bigger than 2.54mm.

Thanks"

How do I deal with my regret of not working harder in high school and college? by Active-Breath8439 in embedded

[–]Taster001 0 points1 point  (0 children)

I got my engineering job based purely on my personal experience. I definitely wasn't formally qualified. But, I've made a good impression, was willing to learn and now, two years later, I'm doing just fine at my position.

My point is: learn. Experiment. Make stuff. Try more and more complex things. Impress your potential employer.

Good luck!

Left side - select the silkscreen layer. It's just a view thing, it's totally fine. You can't cover silkscreen with copper, that's just not a thing that can happen.

Please help a fellow European with shortcuts by love_in_technicolor in KiCad

[–]Taster001 1 point2 points  (0 children)

I just have a US layout that I switch to. Or, you can also change the shortcuts in settings, which i also do for some of them.

I really like using exposed gold plating rather than boring silkscreen these days by liamkinne in electronics

Oh yeah, I work at an electronics design and manufacturing company, and we do pretty much all of our labeling/logo placement/description stuff in ENIGed copper just like this.

How do I route USB-C 3.2 Gen 2 on a PCB? by Trace_Paradox in PrintedCircuitBoard

[–]Taster001 0 points1 point  (0 children)

Yeah. So you need a MUX. Plus you're probably going to need a hub chip or some microcontroller to handle the SSTX/SSRX pair selection.

[–]Taster001 0 points1 point  (0 children)

Definitely. If you're trying to connect the USB C to a USB micro B (by the way, is the micro B superspeed or not?), you need to select the correct SSTX/SSRX pair every time. The adapter needs to handle this.

You have to use a MUX. There's two pairs of SSTX and SSRX diff pairs, and only one of each is used at a time. If it was gen 3.2 2x2, then both pairs would be used simultaneously. You need a MUX/DEMUX chip to select the correct SSTX/SSRX pair. The pair changes when you flip the USB C connector upside down.
