Breadboards are designed and manufactured for solderless experiments of electronic circuits due to the many small jacks on the board. Since various electronic components can be inserted or pulled out at will, eliminating the need for welding and saving the time of circuit assembly, and the components can be reused, it is very suitable for the assembly, debugging and training of electronic circuits.
The name of the breadboard can be traced back to the era of vacuum tube circuits. At that time, most of the circuit components were large. People usually fixed them on a piece of wood for cutting bread by screws and nails. Later, the volume of circuit components became more and more. Smaller, but the breadboard name lives on.
