This Spring 2026 updates make hardware design faster end-to-end with a more capable, self-correcting AI agent, improved AI auto-layout that needs less cleanup, sourcing-aware design with real-time pricing and availability, and templates to start from.
We’ve been so amazed with the ways you’ve used Copilot to brainstorm, debug, and conduct part research that we’ve compiled some of our favorite prompts you can copy and paste, or modify for your own use!
Copilot prompts are natural language inputs given to a custom-trained large language model (LLM) specifically designed to understand the principles and methodology of electronics engineering, circuit design, schematic design and PCB design.
For example, if the prompt is
How would I connect ILI9341 and SPI TFT LCD?
Try it now
the model will generate an answer in a human-like manner based on the prompt. And because Copilot lives inside the PCB design tool, not only it provides direct feedback, advice, analysis, and with your approval - it can take action, through a simple chat interface. With just press of a button, Copilot can connect components together.
The future of hardware design is already here with Flux Copilot, offering a new and faster way for hardware engineers to work, making it more fun as well. Learn more about Flux Copilot.

Discover our latest schematic design updates that streamline wire adjustments, component alignment, and intuitive pin connections, making your design process faster and meeting your high standards for precision. These enhancements, coupled with our AI design assistant, ensure a solid foundation for your projects.
Traditionally, the process of fine-tuning wire positions on a schematic felt akin to rewriting an entire chapter of a novel for just a few key edits. Crazy!
With Flux, the narrative changes. Enabling the meticulous adjustment of wire positions without the need to start from zero, we've introduced a drag-and-drop feature for individual wire sections. This allows you to artfully navigate around objects, symbols, and components, ensuring that every wire is precisely where it needs to be.
We've also tackled the pesky issue of fragmented line segments—those tiny, unnecessary elbows in your schematic that disrupt the visual flow. Now, parallel wire segments snap and merge into a singular, streamlined line. This eradicates clutter, simplifying your schematic into a model of elegance and simplicity.
💡 Tip: you can also use ctrl/cmd+click to select an entire net at once!
We wanted to make creating connections more intuitive and faster. So we created some new ways to connect components and draw wires that’ll have you working at lightning speed.
Now you can connect components simply by dragging them onto one another. Drag a component until one or more of its pins are on top of the pins from another component, then drop it. Instantly, the overlapping pins become connected. You can leave it there, or drag it away to see the wires. For many cases, this could save you two or more clicks, speeding up your workflow.
Connecting components to existing wires is now a breeze. Drag a component until one or more of its pins overlap with the wire, then drop it. Instant connection!
Now you can create connections while adjusting a wire. Drag an existing wire until it overlaps one or many pins of a component, then drop it, and they’ll become connected.
You can create many connections effortlessly while drawing a wire. Draw your wire in such a way that it overlaps multiple pins, then finish drawing. All of the pins will now be connected to the wire! This is super helpful if you have an IC, for example, that needs many pins down a line to be connected to the same net.
We’ve also added new alignment and snapping features, which provide visual guides to ensure that all objects on your schematic are nicely aligned. Just drag two objects near each other and, like magic, guidelines appear to help guide the alignment of your components.
💡 Tip: You can also highlight components and right click and quickly align vertically, horizontally, or space evenly.
Your quest for the perfectly aligned, clutter-free schematic isn't just a solo adventure. Flux Copilot shares your, let's say, 'enthusiastic precision.'
With the power of AI at your fingertips, Flux Copilot transforms the art of schematic design into a collaboration with technology. It's not just an assistant; think of it as your detail-obsessed partner in design. Got two components that need a connection? Just whisper sweet nothings (or, you know, actual instructions) to Copilot, and watch it work its magic.
Copilot is here to help you work not just faster or smarter, but at warp speed towards creating that breathtakingly beautiful schematic. Because in the end, a more readable schematic doesn't just mean easier collaboration—it means creating something truly spectacular, together. Sign up for Flux today.

We’re launching our Stackup Editor: a new and improved way to select your PCB stackup that requires less time, less effort, and is less prone to errors. This is another massive step towards creating a single place where designers can collaborate with each other and the industry as a whole.
Selecting your PCB’s stackup has always been painstaking and unintuitive. First, you have to talk to the fabrication house, who will send you their stackup capabilities and tolerances via email and PDF. Then, it’s your job to take that information and transpose it back into your design tool, double and triple-checking that you didn’t make any errors in the process. So much back and forth inevitably leads to disorganization, information loss, and sometimes even failure. Not to mention lost time in the process.
If fabrication houses have standardized stackups, why are there so many hoops to jump through just to implement them into your design?
With Flux’s Stackup Editor, we change the narrative. With a simple and intuitive interface built into the tool, the Stackup Editor gives engineers an improved stackup workflow. Just go to your PCB layout, select “Stackup” under “Object-specific rules”, and find everything you need in one centralized location.
Not only can you edit and create stackups with minimal effort, but you can now also leverage Flux’s community of over 175,000 electrical engineers to take the hard work out of the process. With thousands of projects available to you from the community, you never have to start from scratch. Instead, you can simply find a project that is similar to yours and use that stackup as a template for your own design.
Finally: stackups no longer live in your email inbox, they live in the tool. And with that, you can save yourself from the wasted time, money, and effort that has been industry-standard for far too long.
More importantly, the addition of Stackup Editor aligns with our ultimate goal of creating a single, centralized platform for all of the hardware industry to collaborate.
With the Stackup Editor, fabrication houses themselves can directly input their stackup options into Flux as templates for designers to choose from. Just go to the fabrication house’s Organization page, find a stackup template from them that matches your project, and fork it for your own design.
At launch, you can choose from dozens of Stackup templates, including:
With that kind of first-party input from the houses themselves, you can feel confident that your stackups are ready for production before you even get there.
The Stackup Editor is another massive step towards creating a single place where designers can collaborate with each other and the industry as a whole. Now Flux offers one place where you can directly access parts from suppliers, designs and references from manufacturers, and stackups from fabrication houses.
If you want to get hands-on with the Stackup Editor, check out some of our templates and get started today!
For months, we’ve been adding new features and functions to Copilot to help make it the most powerful AI for hardware design in the world. Today, we’re announcing what might be the biggest upgrade yet: Copilot Vision.
Now, not only can you chat with Copilot, but you can also show it what you're working on. What does that mean? Copilot is now the first multi-modal AI for hardware design, and with that, a whole new world of possibilities has opened up for Flux users.
Hardware design can be tricky because so much of the thinking is visual and requires context. As an engineer, you’re expected to rely on visual resources like block diagrams, charts, and drawings. But these resources are usually confusing to interpret and separate from your actual design, making them lose their value quickly.
With Copilot Vision, you can now provide Copilot with images as a more natural way to communicate ideas and integrate those resources into your design. Imagine snapping a photo of a block diagram and Copilot instantly understanding what you're trying to build.
Simply provide Copilot an image as a file upload and ask your questions. Suddenly, visual resources are relevant and even powerful for sanity checks. Now, you can ask questions, learn, and get design reviews in entirely new and more effective ways.
Imagine you’re working on a project that’s based on an existing block diagram. You need to turn that block diagram into a working circuit, selecting the right components and connecting them in the right way. Normally this would mean reading through datasheets and application notes, but that gets confusing, time-consuming, and hard to keep track of.
Now that Copilot has vision, you have access to powerful new use cases that improve your hardware design workflow.
Part Recommendations: Trying to find the right parts to implement your design? You can now input a block diagram to Copilot and watch it recommend suitable parts for your design by intelligently parsing the diagram into functional sections.
Design Review: Once you make your design, you’ll want to make sure you didn’t miss anything. Copilot can help ensure design quality by comparing your schematic diagram against a block diagram. Copilot's analysis catches discrepancies, such as missing elements in your design that appear in the diagram, and offers you suggestions for improvement.
Chart Interpretation: Confused about how to interpret a chart on a datasheet? Just provide Copilot with an image of the chart and ask it in-depth questions. It will interpret your input and explain any aspect of the chart and how it relates to your hardware design needs.
Dimensional Analysis for Footprints: Have you ever looked at the part drawings and been overwhelmed by all the information and dimensions? Now you can provide an image to Copilot and ask it any question about part dimensions. Copilot efficiently interprets and correlates them to real component footprints, even making educated guesses about component types based on project context.
This is a major step forward for Copilot, but we’re just scratching the surface of what’s possible. We believe that vision unlocks the doors to so much more down the road, but we’ll need your help! By trying out Copilot with vision, you can help us identify new use cases and steer the direction of Copilot’s future.
