Circuit Breadboards


Breadboards are boards on which one can experiment with electronic components and circuits before the soldering process on a circuit board. Quality and pricing varies, with simple models consisting of just the loose breadboard and more advanced models consisting of mounted breadboards with inbuilt connections for power supply and grounding, signal generators, serial interfaces, display modules and logic probes.


Breadboards got their name from the slab of wood used as a board for slicing bread. Originally, breadboards were literally wooden boards into which nails were hammered to wire electronic components to. However, modern solderless breadboards are plastic boards with a grid array of connection points that electronic components can be plugged into. This makes them reusable and they are commonly used for both prototyping circuits and for educational and training purposes. To keep breadboards in the best possible condition, keep them clean and dry, and if necessary use an air duster.


Breadboards are available in different sizes. The most common size is 830 tie point. Other sizes can range from 170 to 3200 tie point. You can also snap some breadboards together to make a larger board.


Breadboards do not require soldering. Rather, they are involved in the planning and prototyping stage. Once a circuit is created on a breadboard, it can be translated or replicated on a Printed Circuit Board (PCB) and soldered onto it. PCBs come in many varieties, including matching designs to common breadboards, allowing for an easy transfer.

The use of breadboards involves, in addition to the breadboard itself, materials such as wiring, jumper cables, electronics tweezers for precise manipulation of electronic components and electronic components like transitors, resistors, LEDs and switches. Because of the sensitive nature of most electronic components, an anti-static grounding strap is often a necessary purchase.
