Today, we’re excited to share that Flux has raised $37M in new funding, including a $27M Series B led by @8VC, with participation from @BainCapVC, @Liquid2V, and @OutsidersFund.
To the Flux community: we couldn’t have done this without you! Your projects and feedback shape what we build.

A browser tab, a text prompt, and a printed circuit board headed to a factory.

Flux wants to be Figma for circuit boards - and it is closer than you think.

You can save simulation outputs or test data to Files so the agent can reference them in future sessions.
No re-uploading or re-explaining what you already tested.

"Run a Bode plot and tell me the -3 dB cutoff frequency"
Flux generates the frequency sweep, plots gain and phase, and reports the exact cutoff.
Just one prompt.

When the tools work together, engineers stay in flow and ship faster.
Welcome to the future of hardware design.

Designing in Flux just got better 👀
HQ Online is now inside Flux. @BuildWithFlux
HQ Online, NextPCB’s library of 600,000 in-stock components, is now integrated into Flux’s AI-powered PCB editor. Engineers can now check real-time pricing, availability, and in-stock alternatives directly while designing — without leaving the workspace.
With HQ Online inside Flux, you now get:
• Live stock and pricing directly in the design flow
• Instant access to in-stock replacement parts through Flux’s AI search
• A more sourcing-aware workflow from schematic to BOM
• A competitively priced sourcing option for components

Ask Flux to conduct a schematic review and it will generate a full report, findings, flagged issues, and recommendations, saved as a document in the Files tab.
This helps you keep a record of your design reviews so nothing gets lost.

You start a board with a Raspberry Pi, but halfway into power, you change your mind. You want an ESP32 instead!
Today, we’re introducing an upgraded version of the Flux agent that’s more steerable, adaptive, and faster.
Your hand’s on the wheel.

Drafting your spec is painful. Keeping it up to date as your project evolves is worse.
Flux does both, automatically. Updating as you make decisions, so the whole team stays aligned.
The more context the agent has, the better it performs.

Full Tutorial: How To Create Your First Schematic with AI
You know what you want to build. But, the schematic is where it slows down.
Two methods, under 5 minutes: write a prompt, or upload a photo of a datasheet. Flux drafts the schematic, and you review it.

Technical research is hard to keep track of across sessions and chats.
Flux now saves it automatically to Files, structured documents, organized by functional block, always there when you need them.

Every step of PCB design can now be done with AI.
Schematic. Placement. Routing. Board.
One tool. Try it today.

We just shipped AI component placement in Flux.
Watch it place a full board in real time.
It's the first time any tool has been able to do this. And it's only day one.

Flux can now place your PCB components.
You finish your schematic, move to layout, and instead of manually dragging dozens of parts around, you kick off an AI Placement session.
Here's what that looks like on a real board. 🧵

Under 9 minutes. Components placed and ready to route.
It's a real starting point. You skip the most tedious part of layout and get to the work that actually matters.

Placement was the last missing step.
Now every step of PCB design — schematic, placement, routing — can be done with AI in one tool.
No tool has done this before. Try it → flux.ai/signup?destinationPa…

“Place the buttons at the center, usb on the left. Make no mistakes flux”
We just shipped the first AI PCB layout engineer that you can argue with 😆

Flux can now place your PCB components.
Schematic → placement → routing → board. Every step AI-assisted, in one tool.
You steer it. AI builds it. Like vibe coding, but for hardware.
This has never been possible before. Try it now

Stress testing your design has never been easier.
Describe the test conditions in one prompt, and Flux runs all of it.
Voltage sweeps. Current sweeps. Temperature corners. Then, correlating the results to find failure points.
