Overview

Light emitting diodes are diodes that emit light when current passes through them. They are commonly used as indicators on a circuit board such as a "power on indicator" or "data transfer in progress indicator".

Start by asking your AI to “use tscircuit.”

Tell your AI what you want to build. In environments where your AI can install and run tools, it can download and use tscircuit automatically—you usually don’t need to install anything yourself.

Try: Use tscircuit to design a USB-powered LED board.

export default () => (
 <board width="10mm" height="10mm">
  <led name="LED1" footprint="0603" color="red" />
 </board>
)

Properties

Property	Example Value	Description
color	red	The color of the LED. red LEDs are most common.
forwardVoltage	1.6V	The voltage drop across the LED when forward current is applied.

Color Example

Here's an example showing how to use different LED colors in a board layout:

export default () => (
  <board width="10mm" height="10mm">
    <led name="D1" footprint="0805" color="blue" pcbY={2} />
    <led name="D2" footprint="0805" color="green"/>
    <led name="D3" footprint="0805" color="red" pcbY={-2}/>
  </board>
)

Common LED Footprints

The following represent the most common footprints for LEDs based on jlcsearch, you can provide these as the footprint property to the led element e.g. <led footprint="led0603" />

Footprint	~JLCPCB Popularity
led0603	37%
led0805	23%
led1206	10%
led0402	4%

Automatic Part Selection

LEDs are automatically selected according to their color and footprint using the platform parts engine
