Documentation · Website · Twitter · Discord · Quickstart · Online Playground

Features

• 3D visualization of PCB layouts
• Interactive camera controls (pan, zoom, rotate)
• Support for various PCB components (resistors, capacitors, Chips, etc.)
• Customizable board and component rendering

Installation

npm install @tscircuit/3d-viewer

Usage

Basic Example

import React from "react"
import { CadViewer } from "@tscircuit/3d-viewer"

const MyPCBViewer = () => {
  return (
    <CadViewer>
      <board width="20mm" height="20mm">
        <resistor
          name="R1"
          footprint="0805"
          resistance="10k"
          pcbX={5}
          pcbY={5}
        />
        <capacitor
          name="C1"
          footprint="0603"
          capacitance="1uF"
          pcbX={-4}
          pcbY={0}
        />
      </board>
    </CadViewer>
  )
}

export default MyPCBViewer

Using with Soup Data

import React from "react"
import { CadViewer } from "@tscircuit/3d-viewer"
import mySoupData from "./mySoupData.json"

const MyPCBViewer = () => {
  return <CadViewer soup={mySoupData} />
}

export default MyPCBViewer

API Reference

<CadViewer>

Main component for rendering the 3D PCB viewer.

Props:

• soup: (optional) An array of AnySoupElement objects representing the PCB layout.
• children: (optional) React children elements describing the PCB layout (alternative to using soup).

<board>

Defines the PCB board dimensions.

Props:

• width: Width of the board (e.g., "20mm").
• height: Height of the board (e.g., "20mm").

Component Elements

Various component elements can be used as children of the <board> element:

• <resistor>
• <capacitor>
• <chip>
• <bug> (for ICs)

Each component has specific props for defining its characteristics and position on the board.

Advanced Usage

Custom Component Models

You can define custom 3D models for components using the cadModel prop:

<chip
  name="U1"
  footprint="soic8"
  cadModel={{
    objUrl: "/path/to/custom-model.obj",
    mtlUrl: "/path/to/custom-material.mtl",
  }}
/>

JSCAD Models

For more complex or programmatically defined models, you can use JSCAD:

<bug
  footprint="soic8"
  name="U1"
  cadModel={{
    jscad: {
      type: "cube",
      size: 5,
    },
  }}
/>
