Features

• Convert KiCad PCB files *.kicad_pcb to Circuit JSON
• Convert Circuit JSON to KiCad PCB files *.kicad_pcb
• Parse and serialize KiCad schematic files *.kicad_sch
• Support for KiCad project files (*.kicad_pro)
• Robust type checking using Zod schemas
• Easy integration with existing KiCad and tscircuit workflows

Installation

Install KiCad Converter using npm:

npm install kicad-converter

Usage

Here's a basic example of how to use KiCad Converter:

import { convertKiCadPcbToCircuitJson, convertCircuitJsonToKiCadPcb, parseKiCadSch } from 'kicad-converter';

import kicadPcb from "./path/to/your/kicad_pcb_file.kicad_pcb" with { type: "text" }

// Convert KiCad PCB to Circuit JSON
const circuitJson = convertKiCadPcbToCircuitJson(kicadPcb);

// Convert Circuit JSON to KiCad PCB
const newKicadPcb = convertCircuitJsonToKiCadPcb(circuitJson);

API Reference

The library exposes several key functions:

• convertKiCadPcbToCircuitJson(kicadPcb: KiCadPcb): AnyCircuitElement[] Converts a KiCad PCB object to Circuit JSON format.

• convertCircuitJsonToKiCadPcb(circuitJson: AnyCircuitElement[]): KiCadPcb Converts Circuit JSON to a KiCad PCB object.

• parseKiCadSch(sexpr: SExpr): KicadSch Parses a KiCad schematic S-expression into a structured object.

• serializeKiCadSch(kicadSch: KicadSch): string Serializes a KiCad schematic object back into an S-expression string.

Advanced Usage

Working with KiCad Project Files

import { parseKiCadPro } from 'kicad-converter';

const projectFile = // ... load your .kicad_pro file content
const parsedProject = parseKiCadPro(projectFile);

console.log(parsedProject.meta.filename);

Type Checking with Zod

KiCad Converter uses Zod for robust type checking. You can leverage this in your own code:

import { KiCadPcbSchema } from "kicad-converter"

const validatedPcb = KiCadPcbSchema.parse(someData)
// If someData doesn't match the schema, this will throw an error
