Flux | Design PCBs with AI

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.

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. flux.ai/p/blog/new-ste…

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.

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?destina…

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.

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. 🧵

“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.

You can ask Flux to draft a living spec, generate a design review report, or save simulation results, and it stores everything right in Files. Reviewable, reusable, and available in every future session. Try Files now: • flux.ai/p/go/files-tab

Before Files, important context was scattered. Specs in Google Docs, reference files uploaded mid-chat, simulation results buried in old conversations. The AI could only work with what it could see, and most of the time, the important stuff wasn't there. Now it is.

Every Flux project now has a Files tab. A central place where all your project's context lives, documents, uploaded assets, generated outputs, and project descriptions. Everything in one spot, visible to both you and the AI.

Improved: Place pads, silk, holes, and zones directly from the PCB canvas.
