Build PCBs faster with an AI teammate

Go 10x faster from idea to PCB by reducing busy work, never starting from scratch, and keeping your team in sync. Now with the help of Flux Copilot.

Introducing Flux Copilot

Copilot is the new way of working for hardware engineers. It can help you build faster, smarter, and more creatively.

3 separate comment threads. The first one shows a response of Copilot from user's asking for help how to design a USB-C hub. Second is Copilot wiring components together in schematic. Third one is a response from Copilot telling to the user what does pin 32 do on a specific microcontroller.

Brainstorm solutions with Copilot to kick off new projects or debug when you're stuck. Check out our favorite Copilot Prompts.

Let Copilot wire it up. Copilot can suggest and create connections on schematic for you. And that's just the beginning.

Ditch the datasheets by asking Copilot contextual questions like the capabilities of a particular component.

Say goodbye to busy work

Flux eliminates repetitive tasks so that you can focus on the work you’re passionate about.

3 panels of UI. The first shows a list of parameters relating to fill stitching vias, such a the fill stitching density. The second shows a layout of a usb hub, with automated differential pairs, a copper fill, and many stitching vias which have been placed dynamically based on the parameters. The third shows pricing and availability for a part.

Parametric design lets you make quick edits to your layout systemically.

Automatic impedance control does all the calculations for you so all you have to do is connect components.

Realtime pricing & availability of all major distributors - such as Digi-Key, Mouser, and LCSC - without leaving the app.

Never start from scratch

A library that’s actually great - and is filled with re-usable components, projects, and templates to give you a head start.

Several components from the component library displaying information: a preview image of the component; the name; description; the author; metrics on the usage and stars; indicators of whether or not the component contains a footprint, a layout, a simulation model, or a 3D model; the manufacturer part number and a link to the datasheet; live pricing and availability.

Re-use components built by the best engineers in the world instead of making them yourself.

A library you don’t have to manage because it’s in the cloud and requires no tedious syncing.

Use templates for platforms like Arduino, Raspberry Pi, ESP32, and all the others.

Hassle-free design reviews

Flux makes it easy to review work with a single source of truth that lives in the browser and on your phone.

An iPhone with Safari open showing Flux in the browser. Flux shows a detail of a PCB layout with collaborators and a comment thread.

Just like Google Docs, invite others to collaborate while controlling permissions.

Comments capture feedback, even asynchronously, so you can get reviews without a meeting.

Bring the whole team by creating an organizational account. No downloads required.

10x faster from idea to PCB

Make use of re-usable blocks, scripting, and an integrated simulator to reduce the time it takes to go from idea to prototype.

Illustration of sub-layout. Several groups of parts and traces hover above a layout.

Choose specific parts later with generic components that let you you make decisions about MPN, package size, and more, later on.

Re-use sections of a layout, like a USB-C module, to drop in fully functional regions to your design instead of starting from scratch.

A built-in SPICE simulator allows you to check designs as you work. Use popular simulator models and program totally new functionality.

Flux and their AI Copilot will enable more people to design their own hardware. Seeed is gladly joining the efforts by bringing the latest open hardware designs to Flux public library!

Out of all the EDA Softwares I've used, Flux is the most innovative and future-focused. We can't wait to see how much Flux can do within the next few years!

As a one-man hardware startup, Flux lets me work as fast as an entire team.
