siliXon

From an idea
to a real circuit board.

Beginners learn by building. Engineers move faster, with every board checked.

Hardware is hard. Electronics is harder. Not anymore.

Electronics design is locked behind years of studying and experience. Less than 0.01% of the world can design a circuit board. siliXon makes electronics accessible to anyone; if you can describe what you want, you can build it.

Just your ideas in simple English. No constraints required.

Built for anyone, regardless of electronics background.

Two kinds of people use siliXon. People with no experience start designing, learning and practising electronics. Experienced engineers use it to speed up their work without losing accuracy.

You design and build for fun, but electronics are tricky to grasp.

You've built a few projects involving some electronics, but are not confident enough to go all the way. Start with an idea and make changes as you see fit. We teach you along the way.

So far creating my first project for 10 min - onboarding seems quite smooth

I like the self validation and how it explains everything too, makes it easier for me to quickly cross reference and learn on the go

HarshStudent & Hobbyist

Response is very meaningful, I like how it asks you questions to verify and gives you the options to choose the answers with the recommended on the one it thinks is a better option

ChuksFounder

Good so far. It is helpful and gives me advice

HBeta user

I have to say I love the UI and UX, the front end is really fun to interact with, with the little dynamic touches etc

ArnavEngineer

Super helpful and easy to use

TomEngineer

Really good actually better than Flux ai

Two months to four-layer boards with parts on both sides

How siliXon learned to design four-layer boards and place parts underneath, from a first attempt in August to a finished board design in October.

Swinging to comma.ai's podium

Rocky got third place on comma.ai's PCB Golf contest, whose purpose was to get the smallest board possible given a set of components and a scoring algorithm. The only autonomous solution on the podium.

How do I design my first electronic circuit board? (PCB)

Beginner electronics and PCB design made simple: describe your first circuit board in plain English and siliXon picks the parts, places, routes and checks it. siliXon provides the easiest way to design circuits for anyone regardless of experience.

Rocky v1.5 is live

Today we're shipping Rocky v1.5, and it's the biggest jump in quality we've released so far. It's more accurate, far more precise in how it changes your board, and it can now actually see the layout it's working on.

We Asked Over 100 Engineers: Why PCB Design Takes So Long? Here’s What We Found

Having talked to over 100 engineers in the past few months to gain a sense of what problems engineers face while designing PCBs, we found that engineering teams can take, on average, 2–3 months to get a PCB from concept to market-ready.

A brief history of PCBs

A brief history of the PCB, from its inception to its current state.

siliXon, not silicon

Search for silixon and Google may show you silicon instead. We're keeping our name. Here's why, and how to find us: type silixon.io.
