What is 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.

Think of tscircuit as "React for Electronics" It allows you to design real-world electronic circuits using Typescript and React. This is what tscircuit code looks like, instead of creating web element like “div”, you create circuit elements like “chip”, “resistor” or “capacitor”, then instead of rendering a website, we render a 3d circuit (that you can actually order!)

Using tscircuit, you can design things like a fully functional keyboard! Once you've completed your design, you can export it to a manufacturer and order a real, functional circuit board!

Example Circuits

• ESP32 Wifi Breakout Board

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!

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 push
• Simplified, extensible auto-routing for PCBs
• Import footprints and components from third-party sites
• 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)

Can I test this in my browser?

Yes! There is a playground tool!

Do I have to specify the position of every component?

Currently you should specify pcbX/pcbY for components (and nest inside <group />s for convenience!)

We are working on building the equivalent of "flex" and "CSS Grid" autolayout algorithms for PCBs. Wherever an automatic placement is made, you'll be able to override it.

Is the auto-routing good?

We are working towards a state-of-the-art web-based autorouting algorithm. You can follow the progress of our autorouter development on autorouting.com

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

Please create an issue!

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/snippets	The main website, playground and online development environment for tscircuit
@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
