This is a typeCAD package that includes simple access to many passive components.
This package uses a named parameter-like interface. Any parameter can be included or left out. They can be accessed and modified later in code.
import { Schematic } from '@typecad/typecad'
import { Resistor, LED, Capacitor, Diode, Inductor, Fuse } from '@typecad/passives/0805'
import * as _0603 from '@typecad/passives/0603'
let typecad = new Schematic('passives');
let resistor = new Resistor({ reference: "R1", value: "4.7 kOhm" });
let capacitor = new Capacitor({value: "100 nF", voltage: "6 V"});
let diode = new Diode();
let inductor = new Inductor({ value: "2.2 uH"});
let fuse = new Fuse({ reference: "F1" });
let led = new _0603.LED(); // a 0603 instead of 0805
typecad.create(resistor, led, capacitor, inductor, diode, fuse);All of the sizes are:
@typecad/passives/1210@typecad/passives/1206@typecad/passives/0805@typecad/passives/0603@typecad/passives/0402@typecad/passives/0201*no fuses
If { reference } is not included, the component will be auto-numbered. If there are any name collisions, the new name will be suffixed with a _1, ie R1_1.
If auto-designation is used, components have the potential to move/switch/replace each other in the PCB Editor. The first component created will be x1, then x2 and so on. If there is a component added above x1 in the code, that topmost component will now be x1 and the old x1 will now be x2. This will cause them to switch places when imported into the PCB Editor. Specifying the reference for every component avoids this.
Connectors can be created similarly.
import { Connector } from './module/passives/connector'
// create a 10-pin connector using the JST footprint passed in the last parameter
let j1 = new Connector({ number: 10, footprint:"Connector_JST:JST_SH_SM10B-SRSS-TB_1x10-1MP_P1.00mm_Horizontal" });
// create a 5-pin connector using a default 2.54 mm pin-header
let j2 = new Connector({ number: 5 });Testpoints can be created:
import { Testpoint } from '@typecad/passives/testpoint';
let tp = new Testpoint();Will create a testpoint with a default footprint of TestPoint:TestPoint_Pad_D1.0mm.
Specific footprints can be chosen:
let tp = new Testpoint({ footprint: 'TestPoint:TestPoint_Keystone_5015_Micro_Mini'});Connect a testpoint using tp.pin(1) in the ::net() method.
