A 400-point breadboard refers to a type of solderless breadboard that has 400 terminal points or connection points. These breadboards are commonly used for small-scale electronics prototyping and experimentation.
Here are some characteristics of a typical 400-point breadboard:
- Size: The standard size of a 400-point breadboard is usually around 8.2 cm × 5.5 cm, although variations in size and shape are possible.
- Terminal Strips: The breadboard is divided into multiple terminal strips, typically organized horizontally along the length of the board. Each terminal strip consists of multiple interconnected holes, usually in groups of five, allowing you to insert electronic components and connect them.
- Power Rails: A 400-point breadboard usually has two power rails running vertically along the sides of the board. These power rails provide convenient connections for supplying power and ground to your circuit. The positive voltage (usually marked as +) and ground or negative voltage (usually marked as -) are typically distributed along these power rails.
- Breadboard Holes: The holes on the breadboard are where you insert and connect electronic components. Each hole on the breadboard is connected internally in a specific pattern, usually following a grid layout. The interconnected holes within a terminal strip allow components to be easily connected without the need for soldering.
- Versatility: A 400-point breadboard provides a moderate number of connection points, allowing you to prototype small to medium-sized circuits. It is suitable for simple projects and experimentation, accommodating various types of components, such as resistors, capacitors, integrated circuits (ICs), and discrete components.
It’s important to note that the specific design and layout of a 400-point breadboard can vary between manufacturers. However, the general concept and functionality remain the same, providing a convenient platform for temporary circuit construction without the need for soldering.
