typeCAD Schematic

Generate KiCAD schematics from your typeCAD project.

Getting Started

Prerequisites

• a working typeCAD project
• KiCAD installed on your system

Installation

Run the following command in your project directory, where your typeCAD package.json file is located:

npm i @typecad/schematic

Usage

import { PCB, Component } from '@typecad/typecad';
import { schematic } from '@typecad/schematic';
import { Resistor } from '@typecad/passives/0603';

let typecad = new PCB('project');
let r1 = new Resistor({ value: '100k' });                            // using the @typecad/passives package, symbols are defined already
let u1 = new Component({ symbol: 'Sensor_Humidity:SHT4x'});          // other components must have their 'symbol' property set
typecad.create(r1, u1);
schematic(typecad.Schematic);

Output

The schematic will be generated in the ./build directory with the same name as your sheet. For example, if your sheet is named "main", the output will be ./build/main.kicad_sch.

Features

• Automatic symbol library management
• Component placement and connection
• Net labeling
• Grid-based layout
• Support for custom symbols

Component Placement

Using custom components with explicit symbol definitions:

let u1 = new Component({ 
  symbol: 'Sensor_Humidity:SHT4x', sch: { x: 150, y: 100, rotation: 0 } 
});

The symbol property must be set for custom components and should follow the format 'Library:SymbolName'. If sch.x and sch.y are not specified, components will be placed randomly.

Notes

This is in development. Currently, it places components at random and makes an attempt to prevent overlapping symbols. It connects pins through labels, not wires.
