Guide to PCB breadboard for electronic circuit design

By offering a dependable and effective method of creating electrical circuits, printed circuit boards (PCBs) have revolutionized the electronics industry. However, it is imperative to prototype and test the circuit on a breadboard before a final PCB design is created. A perforated board called a PCB breadboard enables the mounting and connection of electronic components for testing and experimentation.

We will go over the many types of breadboard circuits, how they operate, how to create a PCB breadboard, and the distinctions between PCBs and breadboards in this post.

Introduction of PCB breadboard

Electronic enthusiasts and experts can quickly design and test prototype circuits using a PCB breadboard, which is a flexible tool. These boards include a perforated surface that is frequently referred to as a “grid,” and it is this surface that is utilised to mount and connect electronic components.

For convenience, rows and columns of holes are frequently organised onto a PCB breadboard’s holes at regular intervals. It is now possible to install components and connect them via wires or jumper cables, making it simple to design and test various circuit combinations. Because they make it simple for designers to quickly and easily test out new concepts and designs, PCB breadboards are a useful tool for electronic prototyping. By spotting possible problems before a final design is created on a more durable PCB, this can help save time and money.

Additionally, it is simple to change and enhance a design as needed because components can be removed and replaced with ease on a breadboard.

What are the different types of breadboard circuits

Electronic circuit prototyping frequently uses breadboard circuits. Solder and solderless PCB breadboards are the two primary varieties of breadboard circuits. With solder breadboards, components must be attached to the board using a soldering iron. Long-term use is possible with this kind of breadboard because it offers a stable and secure connection between the components and the board. However, once the circuit has been soldered, it can be time-consuming and challenging to make changes because soldering calls for skill and accuracy.

On the other side, solderless breadboards do not require soldering because spring clips are used to secure the components. These breadboards are more frequently used for prototyping since they make circuit adjustments quick and simple. Wires or jumper cables can be simply inserted into the spring clips to link the components, and components can be easily removed and replaced. Solderless breadboards are thus a practical and adaptable choice for testing and experimenting with various circuit designs.

How does a PCB breadboard work

Both professionals and starters in the field of electronics need PCB breadboards. They offer an easy method for attaching and connecting electrical parts, allowing the construction of intricate circuits for varied uses. These breadboards function by providing an array of rows and columns of holes that can accommodate the leads of electronic components.

This architecture enables testing and experimenting without the requirement for a permanent PCB design by making it simple to insert and remove components as needed. Additionally, the PCB jumper or small gauge wires that can be inserted into the holes to connect the components on these breadboards enable quick and simple wiring. PCB breadboards are a useful tool for anyone interested in electronics because of their versatility and simplicity of use.

The way to make a breadboard PCB

The process of designing and making a breadboard PCB is fascinating and necessitates a high level of ingenuity and accuracy. The first step in the process is designing a circuit board layout using software like Eagle or KiCAD, which specifies where components and wires should be placed.

The layout is then laser-printed onto a copper-clad board, and the board goes through an etching process, which eliminates unnecessary copper to reveal the circuitry pattern. When drilling holes for wire and electronic components, accuracy is essential. The designer then places the electronic parts in the appropriate places on the board. Overall, this procedure involves persistence, imagination, and close attention to detail, but the result is worthwhile.

At first look, PCBs and breadboards may appear to be identical because both are used to build electronic circuits. They do, however, have definite advantages and disadvantages and serve various functions. PCBs are permanent circuit boards that are produced to order and are intended for particular applications.

A circuit cannot be easily changed after it has been designed and printed into a PCB without requiring substantial changes or perhaps a complete redesign. However, before a final design is created, circuits are prototyped and experimented with on breadboards. They enable rapid and simple circuit changes by making it simple to add or remove components without the use of special tools or solder.

As a result, engineers and amateurs that need to quickly test and alter circuits should choose breadboards. In conclusion, breadboards are the ideal option for quick prototyping and experimentation whereas PCBs are useful for producing high-quality, permanent circuit boards.

How wide are PCB breadboard holes

Depending on the manufacturer and the board’s intended application, the size of the holes on a PCB breadboard can change. To fit the leads of most electronic components, the holes are typically 0.04 inches in diameter.

What size and spacing are pins on a breadboard

A breadboard often has pins spaced at a 2.54mm pitch, or 0.1 inches, which is another name for this spacing. Depending on the manufacturer and the board’s intended application, the pins’ sizes can vary, but they typically have a diameter of 0.02 inches. Most electronic parts, such as resistors, capacitors, and integrated circuits, may fit in the pins on a breadboard.


Electronic circuit creation and testing are greatly aided by PCB breadboards. They provide a quick, inexpensive method of prototyping by enabling changes to be made to a circuit without the requirement for a permanent PCB design. Whether you are a professional or a hobbyist, knowing the various types of breadboard circuits, how they operate, and how to create a PCB breadboard can make it easier for you to design and test your electronic circuits.
