What is EasyEDA for PCB Design: Overview and Use Cases

EasyEDA is a free, web-based tool for designing printed circuit boards (PCB) and electronic circuits. It lets users create schematics, simulate circuits, and generate PCB layouts all in one place without installing software.

How It Works

EasyEDA works like an online workshop for electronics. Imagine you want to build a model airplane. First, you draw a plan showing where each part goes. In EasyEDA, this plan is called a schematic, where you place electronic components like resistors and chips and connect them with wires.

Next, EasyEDA helps you turn that plan into a real board layout, like cutting and arranging parts on a wooden board. It automatically arranges the paths for electricity (called traces) so your circuit works correctly. You can also test your design with built-in simulation tools to see if it behaves as expected before making a physical board.

Because it runs in your web browser, you don’t need to install anything. You save your projects online and can share or order your PCB directly from EasyEDA’s manufacturing partners.

Example

This example shows a simple circuit schematic code snippet in EasyEDA's JSON format that defines a resistor connected to a LED and a power source.

json

{
  "components": [
    {"type": "resistor", "id": "R1", "value": "1k", "position": {"x": 10, "y": 20}},
    {"type": "led", "id": "LED1", "color": "red", "position": {"x": 30, "y": 20}},
    {"type": "power", "id": "VCC", "voltage": "5V", "position": {"x": 0, "y": 20}},
    {"type": "ground", "id": "GND", "position": {"x": 40, "y": 20}}
  ],
  "connections": [
    {"from": "VCC", "to": "R1"},
    {"from": "R1", "to": "LED1"},
    {"from": "LED1", "to": "GND"}
  ]
}

Output

A simple circuit schematic with a 1k resistor connected to a red LED powered by 5V source.
