There are 10 groups on the usual bread board. The 10 island group usually has three internal connection structures:
1, the left five groups are electrically connected, the right five groups are electrically connected, and the left and right sides are not connected. This structure is usually called 5-5 structure.
2. The left three groups are electrically connected, the middle four groups are electrically connected and the right three groups are electrically connected, but the left three groups, the middle four groups and the right three groups are not connected. This structure is usually called 3-4-3 structure.
3. Another structure is that 10 groups of islands are all connected, which is the simplest structure.

Precautions:
A board consisting of many solderless bread board. Generally, 2-4 pieces of solderless bread board are fixed on the motherboard, and then the power cord of each board is connected together with copper foil in the motherboard. Bread board, a professional combination, also specially designed the sub-power control for different circuit units, so that each board can carry different voltages according to the needs of users. The combined bread board is used in the same way as the single bread board.
The advantages of combined bread board are convenient switching power supply, large area, large test scale, high activity and wide application, while the disadvantages are large size and heavy weight, which are not suitable for carrying and suitable for laboratories and electronic enthusiasts.
