Koekytkentälevyt
Koekytkentälevy, often referred to as a breadboard in English, is a solderless construction base used for prototyping and testing electronic circuits. It consists of a grid of holes into which component leads and wires can be inserted. Internally, these holes are connected in specific patterns. Typically, the two long rows of holes along the sides are connected horizontally, forming power rails. These are useful for distributing VCC and ground connections to various parts of the circuit. The shorter columns of holes in the center are connected vertically in groups of five. This allows for the placement of integrated circuits and the interconnection of their pins with other components.
The primary advantage of a koekytkentälevy is its reusability. Components and wires can be easily inserted
