A solderless breadboard is a board that does not have a motherboard as a base, and does not have a soldered power socket, but can expand a single breadboard. It should be powered on 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 for experiment (the power supply must be disconnected during the process of inserting components). When there are more than 5 components or a group of jacks cannot be inserted, you need to use breadboard cables to connect multiple groups of jacks.

The advantage of a solderless breadboard is that it is small in size and easy to carry, but the disadvantage is that it is relatively simple, the power connection is inconvenient, and the area is small. Large-scale circuit experiments are not suitable. To use it for large-scale circuit experiments, use screws to fasten multiple breadboards to a large board and connect them with wires.

A single breadboard is a breadboard with a motherboard as the base, and a special terminal for the power supply, and even some breadboards that can perform high-voltage experiments with ground terminals. This kind of board is more convenient to use. It is to connect the power supply directly to the terminal, and then insert the components to conduct experiments (the power supply must be disconnected during the process of inserting components). When more than 5 components or a group of jacks cannot be inserted, the A breadboard cable (also called bread line, see Resources) is required to connect multiple sets of jacks.

The advantage of a single breadboard is that it is small in size, easy to carry, and can easily turn on and off the power supply, but the disadvantage is that it has a small area and is not suitable for large-scale circuit experiments.
