Oops! Something went wrong while submitting the form.
temperature and humidity sensor node
It should be a low-power environmental node with a digital T/RH sensor, ultra-low-power MCU
portable speaker/boombox (stereo Class-D)
It should be a compact stereo system with dual Class-D amps (2×10–25 W class), simple DSP/EQ or MCU tone controls
handheld digital thermometer & data logger (K-type/NTC)
It should be a handheld meter with a thermocouple ADC + cold-junction compensation, a secondary NTC channel, low-power MCU with RTC for timestamped logging, microSD for CSV export
compact (FOC) brushless DC motor driver board
The key subsystems are: power stage and gate drive, sensing, MCU, comms, and protection to thermal/mechanical stress; external loads: motors dominate (8W to 12W)
1S Li-ion power module (charger + protection + fuel gauge)
It should be a single-cell power delivery board with a charger + power-path, pack protection FETs (OV/UV/OC/short), fuel gauge with sense resistor and alert pin, thermistor input
constant-current LED buck driver (non-isolated, dimmable)
It should be a CC LED buck, PWM/analog dimming with soft-start and fault flagging, LED voltage monitor

USB-C (PD 12V)
USB-C PD (12 V) — PD controller negotiates 12 V PDO, hot-swap/inrush limiting on VBUS, and standard OVP/UVLO/OCP; supports tens of watts
5 VDC barrel jack
5 V DC barrel jack — Fused/TVS-protected 5 V input add transient clamps and basic EMI care at higher loads
12 VDC barrel jack
12 V DC barrel jack — Fused/TVS-protected 12 V input add transient clamps and basic EMI care at higher loads
24 VDC barrel jack
24 V DC barrel jack — Fused/TVS-protected 12 V input add transient clamps and basic EMI care at higher loads—observe creepage/clearance
solar
Solar — PV panel through blocking/ideal-diode into, to system rails
single-cell Li-ion/LiPo battery
Single-cell Li-ion/LiPo (1S) — On-board 1S charger with power-path and NTC, pack protection (OV/UV/OC/short), and simple fuel-gauge; prioritize low-IQ for long standby
multi-cell Li-ion/LiPo battery
Multi-cell Li-ion/LiPo (nS) — Multi-cell charger/BMS with balancing, direct high-power path where appropriate; monitor pack V/I and thermals
2x AA batteries
2×AA batteries — Primary (alkaline/Li-FeS₂) or NiMH cells with UVLO and reverse-polarity guard

The first AI intern for PCBs
Introducing a new way to work: Give Flux a job and it plans, explains, and executes workflows inside a full browser-based eCAD you can edit anytime.
AI help from idea to PCB
Work with Flux like an engineering intern—automating the grunt work, learning your standards, explaining its decisions, and checking in for feedback at key moments.
01
Plan
Describe what you want to build. Flux understands your requirements and maps out a detailed plan for your approval.
02
Schematic
Flux generates conducts research, generates BoMs and schematics while checking in at key points to get your feedback and direction.
03
Layout
AI places parts and routes your design with awareness of your constraints — delivering layouts you can edit and continue to optimize.
04
Manufacture
Outputs are ready for fab, with sourcing-aware parts suggestions to reduce cost and avoid supply risks.
Ship real hardware
Flux scales from quick prototypes to production-ready PCBs. Explore thousands of forkable projects and templates or brainstorm with Flux.
IoT Devices
ESP32 boards, connected sensors, and gateways.
Wearables
Compact, multi-layer PCBs for consumer devices.
Robotics
Motion control, embedded systems, & power distribution.

Our vision
Taking the hard out of hardware
Unlike software, building hardware is still insanely difficult.If you’re working with atoms, the costs are high, the risks are significant, and the timelines are long.
We founded Flux to make atoms as malleable as bits.We want to take the hard out of hardware, to make it as easy for a teenager to build an iPhone as a website. Read more about Flux manifesto.

Can I import projects from Altium, Cadence, or KiCad?
chevron_right
Yes — schematics from Altium (ASCII) and Cadence (EDIF) import into Flux; KiCad part libraries can be imported to bring your components across. Layout import isn’t supported yet.
Importing projects from:
Can I export for manufacturing?
chevron_right
Yes. Flux exports Gerbers, drill files, BoM, pick-and-place, and standard netlists for fabrication and downstream tools. Exporting projects
Is my data secure?
chevron_right
Yes. Flux encrypts data in transit and at rest and runs on SOC-2–aligned, cloud-native infrastructure with SSO and project-level permissions. Read more about privacy statement.
How capable is the AI — and what are its limits?
chevron_right
Treat it like a fast junior engineer: powerful, but you must review its work. We recommend intermediate PCB experience; Flux explains changes, shows reasoning, and checks in before key steps.
How does Flux perform in the browser?
chevron_right
Flux is built to feel like a desktop-class tool without installs: large, multi-layer designs run smoothly in a modern browser, with real-time collaboration built in. Learn how to setup your browser to ensure the best possible experience.
