⏣ tscircuit - React for Circuits

Docs · Website · Twitter · discord · Quickstart · Online Playground

NPM Version

Make electronics using Typescript, React and AI.

npm install -g tscircuit

tscircuit is a library complemented by a registry, package manager, command line tool and AI electronic design suite that makes it easy to create, share, export and manufacture electronic circuits. It uses React Fiber to render circuits into web pages.

const Circuit = () => (
  <board width="50mm" height="50mm" center_x={0} center_y={0}>
    <MySubcomponent name="U1" center={[0, 0]} footprint="sot236" />
    <resistor
      x={2}
      y={-0.5}
      name="R1"
      resistance="10ohm"
      footprint="0805"
      pcb_x="4mm"
      pcb_y="-1mm"
    />
    <ground x={3} y={1} name="GND" />
    <trace path={[".U1 > .D0", ".R1 > .left"]} />
    <trace path={[".R1 > .right", ".GND > .gnd"]} />
  </board>
)

Getting Started

You can do everything you need to do with tscircuit using the tsci command line tool.

npm install -g tscircuit

tsci dev

Open your browser to http://localhost:3020!

tsci Server Preview

More Features!

  • Preview PCBs & Schematics in your browser
  • Use normal Typescript/React tooling
  • Export Gerbers, Pick'n'Place and BOM for manufacturing
  • Add registry packages with tsci add
  • Publish subpackages to the registry with tsci publish
  • Simplified, extensible auto-routing for schematics and PCBs
  • Generate footprints from text using AI

FAQ

Is tscircuit free?

tscircuit is completely free and MIT-licensed open-source

How does this work?

tscircuit uses the same thing that React Native and react-three-fiber use to render to mobile or 3d to render PCBs and schematics (it's called React Fiber!)

You can render schematics or PCBs in any React project like this:

import { Schematic } from "@tscircuit/schematic-viewer"

export const MyApp = () => (
  <div>Regular web react here!</div>
  <Schematic>
   <resistor name="R1" resistance="10k" />
  </Schematic>
)

tscircuit has a bunch of extra tools and exports in the command line, so it's a bit easier to use tsci dev to develop circuits (you can always publish and import them later)

Is this ready for production?

No! Although I've ordered a fully assembled circuit (source code), this project is still very very early!

How does the registry work?

The tscircuit registry fully implements the npm registry. When you run tsci init a .npmrc file is created in your project so that any npm add or npm install for a package starting with @tsci/* will go to the tscircuit registry instead of the npm registry.

# Example .npmrc
# This line says "any package from the org @tsci should use the tscircuit registry server
@tsci:registry=https://registry-api.tscircuit.com/npm

Can I use a different registry?

Yes! You can use the same trick and modify the .npmrc file for your project. You can run your own npm registry with verdaccio

Why are some things upside down?

If you see something upside down, it's because mid-April the Y Axis was flipped so that "up" would mean the Y value would increase for both schematics and PCBs. In web development, the Y axis is negative as you go up, but this probably isn't a good choice an engineering tool so now the Y Axis is positive and some things are upside down until they're fixed.

Can I test this in my browser?

Yes! There is a playground tool!

Do I have to specify the position of every component?

I'm working on autolayout functionality where you will hopefully only need to tweak things like the spacing. The goal of anything auto

Is the auto-routing good?

The auto-routing is very basic. You can adjust the paths by adding pcb_route_hints to a <trace />. Over time, we'll get good, fast auto-routing algorithms and also ways to "bake & cache" a route over a longer time period.

Can I export into other tools for routing?

This isn't currently possible but a major current objective. If you're interested in writing a module that can convert tscircuit soup JSON into another editor's format, reach out on our campfire!!

I found a bug or have an idea for a feature, what should I do?

Please create an issue!

How can I follow along?

Does this use AI?

No, but AI is pretty good at generating circuits! Try it with copilot!

What big features are coming?

  • Type-safe traces
  • Autolayout and autorouter improvements
  • Layout and route "baking" for more complex routes/layouts
  • Lots and lots of static analysis
  • SPICE output!
  • Export to other EDA tools
  • Less bugs! A lot less bugs!

Development Sub-Projects / Organization

tscircuit includes a lot of different independently-runnable sub-projects. Here's a quick guide to navigating all of the sub-projects:

Core Libraries

Project Description
tscircuit The main package, packages up everything into a single version
@tscircuit/builder A typescript-native library for building circuits (no React). Converts typescript into "the soup format"
@tscircuit/cli The tscircuit command line tool tsci and development environment
@tscircuit/schematic-viewer The Schematic renderer
@tscircuit/pcb-viewer The PCB renderer
@tscircuit/react-fiber Bindings from builder to React, React types
@tscircuit/routing Routing algorithms for schematic and PCB traces
@tscircuit/autolayout Layout algorithms for schematics
@tscircuit/footprinter DSL for creating footprints
kicad-mod-converter Convert kicad_mod files to and from JSON
@tscircuit/kicad-viewer View the KiCad official footprints online
