Use

1. Import the package

import { PCB, Component } from "@typecad/typecad"
import { rd_esp32s3 } from "@typecad/rd_esp32s3";

2. (optional) Declare a Power object to power the ESP32-S3

let vin = new Power({...});

3. Make the package.

let typecad = new PCB('rd_esp32s3_implementation');
let esp32s3 = new rd_esp32s3({ pcb: typecad, externalPower: vin });     // pass optional externalPower object

4. ::create() it

typecad.create(...esp32s3.components);

Passives

The default size for the passive components is 0603, but it can be changed by passing a different set of passives.

import * as _0805 from '@typecad/passives/0805';
let esp = new rd_esp32s3({schematic: typecad, passives: _0805});
