Inside EasyEDA, your engineers manually place parts, then route every board. For Flux, you specify the requirement. The AI engineer chooses the parts, generates the schematic, then routes the board.
Flux functions as the autonomous hardware engineer on your team. Provide a requirement. It organizes the design and picks out the parts. It generates the schematic and does board routing. It engineers the mechanical parts and builds the firmware. It evaluates its own work via design rule checks and simulation. Lastly, it supplies files ready to manufacture to your engineers.
EasyEDA is PCB design software that opens in a web browser. A desktop client is also available.[1]
EasyEDA covers schematic capture, simulation based on LTspice, PCB layout, and fabrication files, with an integrated PCB fabrication and component purchase workflow.[1]
EasyEDA opens in any HTML5 web browser on Linux, macOS, or Windows. A desktop client is also available.[1]
EasyEDA supports real-time team cooperation, online sharing, and thousands of open-source projects.[1]
EasyEDA connects the design to PCB fabrication and component purchase in one workflow.[1]
Flux chooses components from 734,000+ public parts. The AI creates the schematic, places these parts, and performs board routing like an experienced designer. Next, it evaluates this design against every datasheet. The system conducts full-wave electromagnetic and circuit simulation. Flux does not rely on just one distributor or just one fabricator. It displays inventory and live prices across several distributors. The software acquires quotes from fabricators you pick. Your engineers examine and modify the result.

Start a Flux project free and describe the device you want to build.
Flux works like an expert engineer to place the parts and route the board. It follows your layout rules and your design intent.
Flux chooses from 734,000+ public parts. Before it places a component on the board, it confirms real-time prices and inventory across distributors.
Flux uses your fabricator's capabilities and your layout rules to validate every board.
For every part, Flux examines the datasheet to validate the design against its limits, ratings, and pinouts.
Upload your EasyEDA project and tell the agent to update it. Then, send it to manufacturing: Flux provides the necessary files for your manufacturer.

Onshape Import 3D models, complete projects, and part libraries. The import preserves parts, schematics, and placement, plus routing from most formats.
Engineers can change imported designs without delay. Say "move the USB cutout 3 cm left" or "make the enclosure tighter", and Flux applies the changes.
Flux gives you the files necessary for your manufacturer. The board files are ODB++, IPC-2581, Gerber, pick-and-place, and bill of materials. For the mechanical parts, you receive 3MF, STL, or STEP.
Orchestration
Give Flux a complete product. Then, the lead AI engineer separates it into workstreams. The AI begins parallel tasks across projects, directs them, and delivers a report.
A separate agent executes every distinct workstream. The main board, the daughterboards, and the enclosure finish simultaneously.
From one location, the lead engineer initiates work on other projects and monitors it all.
It observes every process and redirects work that departs from the brief. It collects the outcomes.
Relocating an interface or adjusting board dimensions requires your approval.
Flux prepares a distinct brief for every board. This document defines the connectors, mounting holes, outline, and aligned enclosure openings. The software assigns one AI engineer and a unique project to each board, developing all three designs concurrently. Next, Flux positions the finalized boards inside the main assembly. The system measures connector alignment and clearances using millimeters.
Verification lab
Flux does more than produce designs. To simulate and test its own work, the AI engineer applies professional-grade solvers and provides the results to you.
The AI engineer runs and reads SPICE simulation on analog, power, and mixed-signal circuits.
Full-wave simulation to analyze the routed board for S-parameters, antennas, impedance, and crosstalk.
Verify electrical and manufacturing rules for every board and schematic.
Analyzes all part datasheets to confirm the design satisfies their pinouts, ratings, and limits.
Simulate airflow and heat for enclosures and boards before you build them.
Test cooling and airflow through the enclosure to verify fans, vents, and heat sinks operate before the first prototype.
Finite-element stress analysis covering mounts, enclosures, and brackets.
Sourcing
Flux interfaces directly with major distributors of mechanical and electronics parts. The AI engineer identifies chips, connectors, screws, and standoffs currently in stock. It examines prices across various distributors. Before the product reaches production, the AI engineer replaces parts at end of life.

Flux acquires estimates directly from the fabricators. They cover 3D printing in plastic and metal, CNC machining, sheet metal, laser cutting, injection molding, casting, wiring harnesses, and circuit boards and assembly. The AI engineer analyzes the price alongside lead time. It examines designs according to the rules of every fabricator. When engineers modify a design, Flux maintains a current quote.

MiniProto One project contains the firmware, the mechanical parts, and the board. This agent can modify the mechanical parts and the board at the same time. Engineers do not move files across a mechanical tool, a code editor, and an electronics tool.
Flux requires zero installation and zero license server administration. It functions on every computer through a modern web browser.
Send a link to grant access. Several engineers can edit the project concurrently. Nobody transfers files via email or questions what the latest version is.
The product receives new AI models and new features. You do not need to install a new version, and you do not relocate your projects.
You do not create a part library before work begins. The Flux library offers 734,000+ public parts.
Send a link to invite engineers. Project-level permissions and single sign-on control visibility.
One platform
Flux does not operate as disconnected CAD applications. It delivers one AI-native engineering platform. Here, engineers from every discipline use an identical project and the same data alongside the same AI engineer.
Create mounts, brackets, and parametric enclosures that match the connectors and mounting holes of the real board. Upload your own STEP models. One parts library supplies the whole product. It contains chips and connectors, devices not positioned on the board, and mechanical hardware, including standoffs and screws.
Firmware for boards designed in Flux, targeting Arm Cortex-M, RISC-V, AVR, or Pico, then compiled, analyzed, and unit tested.
Model-agnostic AI
Flux integrates frontier AI models into a modern agent framework made for CAD and EDA. These models perform the reasoning. Flux brings the project context, workflows, and engineering tools necessary to build working hardware from this reasoning.
Adaptive breaks every engineering job down into separate tasks. It matches each task with the model that delivers high performance for the price. Frontier models process hard design decisions. Fast, low-cost models complete the routine work. Independent tasks operate at the same time, so complete devices are ready faster. Your team collaborates with one AI engineer. Flux directs these job assignments in the background.
Inside Flux, your team can use the frontier models they already trust.
Flux provides its project context, specialized engineering tools, and workflows to every model.
Your team gets an improved model when it launches and keeps the same engineering platforms.
Your engineering capacity must not depend on only one model provider.
Adaptive selects the appropriate model for each engineering step. The work ranges from deep design decisions down to routine checks.
For learning and evaluation, with light AI usage and unlimited manual editing.
For active hardware projects, with included AI usage and additional usage available.
For larger projects and heavier AI usage, with hands-on support from experienced electrical engineers.
For teams on shared projects, with pooled AI usage, member seats, and priority support.
