Hardware changes break firmware
A board revision can leave firmware out of sync with its pins and peripherals.
Firmware teams
Firmware that matches the board.
Flux writes the firmware from the schematic, so pins, peripherals, and parts are right the first time.
Your problems
Pin maps are copied by hand
Pin maps and register settings are copied by hand from schematics and datasheets.
Firmware arrives late
The first board can arrive before its firmware is ready.
Firmware
What firmware teams need from Flux.
Firmware that matches the board.
Flux writes the firmware from the schematic, so pins, peripherals and parts are right the first time.
No more pin maps by hand.
Pin maps come from the schematic, not from a spreadsheet.
Hardware changes that do not break firmware.
When the board changes, Flux updates the firmware to match.
Firmware that builds and passes tests.
Flux builds the firmware and runs unit tests.
Start before the board arrives.
Firmware starts with the schematic, not after the first boards come back.
Your chip families.
Arm Cortex-M, RISC-V and other microcontrollers.
End to end
A unified AI engineer across the product lifecycle.
Flux manages complete hardware development within a single project. One AI engineer guides the device from product requirements to production outputs, while your team reviews each phase.
System requirements
Begin using product specification sheets, high-level block diagrams, or written briefs.
Schematics and component selection
Flux selects purchasable parts and draws complete schematics.
PCB layout design
Flux positions components and routes traces matching your design rules and fabricator constraints.
Enclosures and wiring harnesses
Flux models housing enclosures, mounting brackets, and internal cable harnesses matched to board geometry.
Embedded firmware
Flux writes and validates firmware for the board it designed.
Verification and production packages
Flux executes automated simulations and design checks on changes, then outputs Gerber, ODB++, IPC-2581, STEP, and BOM files.
Model-agnostic AI
Top-tier AI models combined with specialized engineering tools.
Flux links leading AI models with an agent environment engineered for CAD and EDA. While models handle reasoning, Flux supplies project context, engineering capabilities, and workflows to convert logic into working hardware.

Advanced capability at 30% reduced cost.
Adaptive divides each engineering job into tasks and assigns them to the most cost-effective model available. Complex architecture choices rely on top models, whereas routine tasks use rapid, economical options. Parallel processing executes separate steps simultaneously to speed up device completion. You interact with a single AI engineer while Flux manages background execution.

All leading models in one place
Access the top AI models your team depends on directly in Flux.
Hardware capabilities integrated directly
Each model utilizes Flux domain tools, design context, and engineering workflows.
Adopt new models without migration
Gain access to upgraded models without switching engineering platforms.
Avoid vendor dependency
Prevent reliance on a single AI provider for your hardware development pipelines.
Ideal model for each task
Adaptive assigns every task to its optimal model, covering everything from core architecture to routine checks.
Kernel-agnostic CAD
Builds each part on the right CAD kernel.
Legacy CAD software relies on a single geometric kernel, passing its boundaries to every component. Flux operates independently of specific kernels or AI models. The AI engineer selects the ideal kernel for each object, swaps kernels when needed, and merges every piece into a single assembly.

Automated rule checks
Performs electrical and manufacturing verification across all schematics and PCB layouts.
Datasheet verification
Scans the datasheet of every component to validate pin mapping, operating limits, and electrical specs against the design.
Orchestration
A single prompt commands multiple AI engineers.
Provide Flux with product specifications. A primary AI engineer divides the workload into streams, launches parallel project threads, coordinates progress, and summarizes findings.
Parallel execution threads
Every task operates inside a dedicated agent thread. Main PCBs, auxiliary boards, and mechanical housing develop concurrently.
Multi-project tracking
The lead AI engineer initiates secondary projects and monitors all activity from a unified view.
Automated coordination
It tracks active threads, corrects deviations from design goals, and consolidates final outputs.
Full engineer oversight
Modifications affecting physical dimensions or interface connections require explicit user approval.
System architecture with three expansion boards
Flux generates separate design briefs detailing board outlines, mounting points, connector positions, and enclosure cutouts. Each expansion board is assigned to a dedicated AI engineer within its own project for simultaneous development. Flux then inserts completed layouts into the main CAD assembly to verify connector alignment and millimeter clearances.
Collaboration
Unify developers, external partners, and AI agents inside a shared project.
Flux operates directly in your browser. All contributors access identical live files simultaneously without exchanging offline documents.
-
Edit together in real time.
Engineers, reviewers, and AI agents edit within the same project. Active users and their selections remain visible.
-
Automatic version history tracking.
Flux logs all modifications alongside author and timestamp. Revert to previous states or branch them into new projects.
-
