🚨 Electrical engineers are going to hate this. Someone just turned React into a circuit board factory. Write code. Get a real PCB manufactured and delivered to your door. It's called tscircuit. React for Electronics. No Altium. No $10,000/year licenses. No 6-month learning curve. You write React components. But... instead of and , you write , , and . The same way you build a website. That's how you build a circuit board now. Here's what this thing actually does: → Design real circuit boards using TypeScript and React → Edit code in your IDE, watch the circuit update in real time → Auto-generates schematics, PCB layouts, and 3D previews from your code → Automatic part selection and bill of materials generation → Built-in autorouting algorithm for PCB traces → Export to Gerber files and send directly to a manufacturer → Online playground. Design circuits in your browser right now. Here's the wildest part: The creator wrote 40 lines of TypeScript. From that he got a full PCB, a schematic, and a 3D preview. Then he exported it, sent it to a manufacturer, and got a real working circuit board delivered. 40 lines of code. A real physical product. This is free. Write React. Get hardware. $20K+ in bounties already paid to contributors. 8 years in the making. 100% Open Source. MIT License.show more

Does it solve for inductive coupling, ESD tolerance, and EMI or just layout? EE is more than just putting the legos together.

good question, right now it handles layout and routing but the deeper EE stuff like EMI and ESD still needs manual work

Repo:

Electrical engineers aren’t going to hate this. They’re going to underestimate it. Until a 19-year-old ships hardware faster than they can open Altium. We went from: “learn this tool for 6 months” to: “npm install → build a real PCB” The craziest part isn’t React for circuits. It’s that hardware just became iterable like software.

the npm install to real PCB jump is what makes this feel like a completely different era for hardware

This is where software starts collapsing into the physical world. The idea that you can go from React code to a manufactured PCB in one workflow is a massive abstraction shift. Tools like this don’t just speed up engineering, they redefine who gets to build hardware.

well said, lowering the barrier to hardware is going to bring in a whole new wave of builders who never touched a PCB before

Don’t get me wrong, this is like vibe coding in 2018. It’s just a toy. One day will be a real flow, now it is toy only. I’m electrical engineer and I don’t hate. Exactly the opposite. I’m eager for it to be a real flow.

You pay 10kUsd for the ability to design DDR5 busses and simulate 50GHz signals on multi-layer pcbs. With this you will get bit errors on a MHz uart.

react for pcbs is not what i expected today

nobody expected it but here we are, 2026 is wild

It will be great for these tools to become more robust. Our experience so far is they don’t do the best job on more complex multi-layer pcbs. But they’ll get there some day, probably very soon!

multi-layer support will be the real test, but for simpler boards this is already a huge time saver

There is more to a PCB than connecting dots. And text based netlists to define a design has been around for decades, that’s how Berkeley created SPICE. It’s a neat project though.

The gap between software engineers and hardware engineers… just got a lot smaller.

exactly, the line between the two is blurring fast and tools like this are speeding that up

Pretty sure there's a lot more to circuit boards than simply gluing operant functionality together.

true for complex boards, but for simpler projects this removes a huge amount of friction to get started

Good stuff. I'd add some quasi-LLM layer to help newbies understand what they're building.

insane that 40 lines of react prints actual hardware. altium is just a dead bottleneck now. once ai agents start writing tscircuit, pure compute will literally print atoms.

we're getting closer to that every day, the gap between code and physical products keeps shrinking

I think this is a much better approach to automation of simple PCB’s which the incumbents of PCB design software have struggled heavily with in the past.

the old tools made simple boards way harder than they needed to be, this fixes that

It is coming but not yet. These are the first steps.

Personally don’t see the benefit learning a frontend language when there is a better tool available built on the fundamentals of electronics. Cool project. Useful tool, but I don’t see how this threatens EEs

it's not about replacing EEs, it's about giving non-hardware people a way to prototype simple boards quickly

recycling react tsx is the funniest and smartest move in the age of ai, see also @FUCORY

idk i’d have to learn react but i already know how to use kicad

This lowers the barrier a lot

that was the whole point of sharing it, more people should be able to build hardware without expensive tools

code to atoms pipeline. this is where software actually eats hardware

code to atoms is a perfect way to describe what's happening here

write JSX, receive a physical circuit board in the mail. we're speedrunning the "software is eating hardware" thing now and I'm genuinely terrified and excited.

terrified and excited is the right reaction, this kind of thing was not possible a few years ago

the barrier between "i have an idea" and "here's a working prototype" is basically gone now. wild time to be building anything

Electrical engineers wouldn't give a hoot. They work on power generation and transmission. Electronic designers might.

@Ben_Aguero do you hate it yet? Or does it happen after graduation?

@bardozVAL pretty sick

Yeah, 40 lines of code to pattern-place two unique components. For now, EEs don’t hate it - they’re laughing. I like how DIY people are in awe of pretty much everything. “Revolution!” “Altium is obsolete!”

This is sick!

@willreil

Intresting but i cannot can

Why tf would i hate this? This makes my job so much ₿etter

Enginneer? Happy !

great breakdown nav

glad you liked it!

This author is totally detached from the topic

react for circuit boards is such a wild crossover but honestly hardware design tools being locked behind $10k licenses needed to end a long time ago

Why should EEs hate this? Everyone can do this and much more complex PCBs with excellent open source eCAD software. There is no gatekeeping.

Wait until u find clojure >scad > 3d printing ! 😝

I did complete framework that you can build your electronic ,electric or mechanic device just prompt it . Framework making full body ,electronic and mechanic parts that you can add to cart and order to home
