That's why we're partnering with Seeed Studio. Together, we’re making it incredibly easy to bring your ideas to life.
With Flux, you can start with a ready-made project or a tailored template, customize it using Flux Copilot, and then let AI Auto-Layout handle the rest. Once your design is complete, Seeed takes over, fabricating, assembling, and shipping your project—at no cost.
The Seeed organization in Flux has everything you need to get started:
These are complete, functional designs you can use as a starting point:
If you’re building something unique, start with one of Seeed’s board templates. These templates include footprints, pinouts, and configurations, so you can get to designing faster without starting from scratch.
Once you’ve cloned a project or chosen a template, Flux Copilot helps you make it uniquely yours. Adding components, swapping LEDs, or refining connections. You can drop in new parts, and Copilot will automatically guide you through their placement and configuration, ensuring your changes fit seamlessly into the existing design.
It’s like having an expert engineer on your team, guiding you through each step. Learn more about Copilot.
Once your schematic is complete, it’s time to move on to the layout. Traditionally, this step can be tedious and time-consuming, but Flux’s AI Auto-Layout changes the game. Instead of routing traces manually, Auto-Layout optimizes your board in minutes.
The AI intelligently routes components, generating clean, manufacturable designs with no extra configuration needed. During the optimization process, you’ll see multiple iterations of your design as the AI progressively improves the layout. Once it’s complete, you can review and select your preferred version, with the assurance that every option is optimized for manufacturing.
Here’s the best part: through the LED Remix Campaign, Seeed will manufacture and assemble your project—for free.
Create an LED-based design using a Seeed XIAO board in Flux, then submit to Seeed. Their Fusion service ensures your board is produced with high-quality standards and ready to use. Flux and Seeed work seamlessly together, with templates and ready-made projects optimized for manufacturing from the start. Export your Gerber files in just one click, and let Seeed handle the rest.

With Flux and Seeed, it’s never been easier to design, iterate, and manufacture PCBs. Start faster, and bring your ideas to life.

A practical guide to calculating PCB trace resistance, covering the core formula, how geometry affects resistance, worked examples, and design tips to minimize voltage drop and heat.

A practical guide to diagnosing and fixing PCB failures, covering common symptoms, a step-by-step debugging workflow, essential tools (multimeter, oscilloscope, logic analyzer, thermal camera), a pre-power-up checklist, and the design mistakes that most often lead to broken boards.

A practical guide to PCB impedance control, covering why it matters for signal integrity, the four physical variables that shape trace impedance, and how to enforce impedance targets from stackup planning through routing and fabrication.

A practical guide to reducing EMI in PCB design through grounding, return path control, shielding, and layout best practices. Covers EMC compliance with CISPR 32 and FCC Part 15.

A step-by-step guide to designing accurate PCB footprints — covering pads, silkscreen, courtyards, IPC-7351 density levels, origin setup, and common mistakes to avoid.

A practical guide to PCB grounding techniques — ground planes, return paths, star grounding, and analog/digital partitioning — with best practices for reducing noise and improving signal stability.

A practical guide to designing multilayer PCB stackups for signal integrity, EMI control, and stable power delivery. Covers layer types, controlled impedance, common mistakes, and how modern tools simplify the process.

A look at how AI is reshaping PCB design by automating routing, placement, and signal integrity checks so engineers can focus on architecture and higher-level decisions.
