Yes, I am using KiCad since last 4 years. But not sure about advanced PCB design, for example high speed design. Does anyone have experience?
One feature I wish kicad should have is multiple PCBs for one project.

@Petr Dvořák high speed design?

KiCAD is a rockstar! There's nothing that limits it from high-speed design. Just that the high-speed design features like length-matching of differential pairs aren't very interactive and friendly but does the job. Also, I observed that there is a lot of room for optimization in layer switching, speed of routing etc. as the board goes denser (talking about anything above 12 layers)

Navadeep•2/15/24, 3:24 PM

The resolution for this I use is to make the design blocks modular(both in schematic and layout). Create several projects(sch and layout) of the blocks that you think is possibly repeatable. For example: a TPS5432 switching regulator block designed once following datasheet guidelines.
Then as you want to include it in different main projects, add a hierarchical sheet and give the schematic path of that common repeatable block you created. You can apply the same layout multiple times as well in the board.

We use git source control here to navigate across projects i.e, different repositories and a common folder having all these modular block projects which can be used through hierarchical sheets. This partially addresses your problem by not making you do the same thing multiple times in multiple boards/projects.

So if I add another project, block, into a hierarchical sheet of other project will it also copies the layout or just schematic?

Navadeep•2/15/24, 4:34 PM

Just schematic. For layout you got to do separately during that phase of the design. There is a inirect way to do that - replicate layout using KiCAD plugin(not an official feature yet). This plugin allows you to click on any component(in the layout) from the block you replicated and hit on the apply button through that plugin https://github.com/MitjaNemec/ReplicateLayout (i use a different flavor of this plugin customized for the use case)

Yeah right...they're quite a growing semiconductor company now - ramping up from the last 4 quatres. Stock valuation doubled in value in 2023.

Cool fact: the newest Arduino comes with RA4M1 (haven't seen it around a lot though) https://store.arduino.cc/products/uno-r4-wifi

Anything but random - curious about tech stuff. Got a topic to bring up?
#dev-chat revolves around whatever one can talk from a developer standpoint.

Anyone who is building something low power?

pallavaggarwal•2/15/24, 5:54 PM

Hardware or firmware?

techielew•2/15/24, 9:50 PM

What's up Swapn! Welcome! Can you tell us a little about your background? Why do you want to make a Tesla coil anyway?

Ppallavaggarwal Hardware or firmware?

techielew•2/15/24, 9:52 PM

Relative question, but I know that @controls4all is working on building automation solutions based on BeagleBoard, @JKridner actually makes BeagleBoard, @gy4nt works at Balena and probably has a bunch of connections building low power devices. Why do you ask?

techielew•2/15/24, 10:06 PM

Hey @Software Integration friends, there's a new DevHeads Demo out on buildroot/menuconfig with our @abhishek awasthi. If you've got 5 minutes, check out the discussion thread (📦-middleware-and-osDevHeads Demos: Navigating the Buildroot Menuconfig) or the YouTube vid: https://youtu.be/z3CS7xuMwFs !

DevHeads Demos: Navigating the Buildroot Menuconfig

If you want a specialized Linux implementation, you want buildroot. It allows devs to trim the fat off the normally-bloated Linux operating system by selecting only the packages they need for a particular application — and thereby reducing footprint and boot time.

If you're new to buildroot, one of the first things you'll encounter is the menuc...

Some updates about the Tiny Scarab board:

- The first prototype arrived, was tested and it works.

- The enclosure design is ready, including the "graphical overlay membrane". I'll get them produced asap in China.

That's a good idea. I had been thinking that such things would just go in the #dev-heads-feed or similar. Maybe the Events tab, though that might get confusing.

Perhaps we create a "resources" channel... What says the group?

techielew•2/16/24, 1:39 AM

Hey guys :waving_hand:
A little over 12 hours 'til our next meetup and we have a topic this week I think everyone will enjoy: "Who is Your Engineering Hero? Identifying, Engaging & Maximizing Technology Mentors"

We hope you'll join us and share. Here's the meeting thread in case you want to drop some thoughts in before, after, or if you can't make it: https://discord.com/channels/1130679493799977062/1207862407028932659

Umesh Lokhande•2/16/24, 10:50 AM

Sure, it can be done with CH32V003. All you need is plenty of GPIO Pins for buttons and I2C Pins for OLED Display that's all. Firmware is also very simple. I'll drop the circuit & code later today in case you wish to review. I skipped some capacitors in my case to avoid hand solder.
