Use

1. Import the package

import { Schematic, Power, PCB   } 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 esp32s3 = new rd_esp32s3({ schematic: typecad });

4. ::add() it

esp32s3.add();

Default Layout

This package contains a default layout for all the components. The PCB class can be shared between multiple packages.

...
let pcb = new PCB('rd_esp32s3_implementation');
let esp32s3 = new rd_esp32s3({schematic: typecad, pcb: pcb });
esp32s3.add();
esp32s3.place();

After building, there will be rd_esp32s3_implementation.kicad_pcb file in the build directory. Keep in mind that each time esp32s3.place() is called, the layout will be updated with the default component locations, discarding any changes you may have made. Setting it once, building, then removing it is the recommended workflow.

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});
