What Is a Breadboard?

The breadboard is 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 as required, welding is eliminated, circuit assembly time is saved, and components can be reused, so it is very suitable for the assembly, debugging and training of electronic circuits.

Breadboard

Breadboard without soldering breadboard

A non-welded breadboard (above) is a motherboard that does not have a base, and has no welding power outlet, but can expand a single breadboard. It should be powered before use. Connect the two poles of the power supply to the jacks on both sides of the breadboard, and then you can plug in the components (the power must be disconnected during the component insertion). When more than 5 components or a group of jacks cannot be inserted, you need to connect multiple groups of jacks with a breadboard cable.

The advantages of non-welded breadboard are small size and easy to carry, but the disadvantages are relatively simple, inconvenient power connection, and small area. Not suitable for large-scale circuit experiments. If you want to use it for large-scale circuit experiments, you need to use screws to fix multiple breadboards on a large wooden board, and then connect them with wires.

Breadboard Single Breadboard

A single breadboard (below) is a bread experiment board with a mother board as a base and dedicated terminals connected to the power supply, and even some that can perform high-voltage experiments. This board is more convenient to use, that is, directly connect the power supply to the terminal, and then

Insert components for experiments (the power must be disconnected during the process of inserting components) When more than 5 components or a group of jacks cannot be inserted, you need to use a breadboard connection cable (also called breadline, see references) The group jacks are connected.

The single breadboard has the advantages of small size, easy carrying, and convenient power on and off, but the disadvantage is that the area is small and it is not suitable for large-scale circuit experiments.

Breadboard combination breadboard

The combination breadboard (below), as the name implies, is a board made up of many non-welded breadboards. Generally, 2-4 solderless breadboards are fixed on the mother board, and then the copper wires in the mother board are used to connect the power wires of the boards together.

It also designed sub-power control for different circuit units, so that each board can carry different voltages according to user needs. The use of a combination breadboard is the same as a single breadboard.

The advantage of the combined breadboard is that it can conveniently turn on and off the power, has a large area, can carry out large-scale tests, and has high mobility and wide use. use.
