Description

Circuit system and its development board structure, power connection board

Technical field

The present invention relates to the field of circuit technologies, and in particular, to a development board structure, a power connection board, and a circuit system based on the development board structure and a power connection board.

Background technique

In the field of electronic circuits, complex systems are mostly composed of multiple functional modules. Based on the modular design, the entire system can freely add, delete or replace functional modules to achieve a flexible system structure.

The embedded development learning board is mostly in the form of a single board. Since it is necessary to meet the needs of various learners and developers, it is often necessary to integrate as many functional modules as possible on a single board, and this is often not required for a specific user. The multi-function module, for the user, has to pay for the function that is not required, which obviously causes a great waste. If you need to use the function modules that are not in the learning development board, you need to purchase the corresponding development board separately, and there is no update upgrade capability. If the function module needs to be expanded, it is necessary to solder the electrical connection between the main board and the extended function module, which is both cumbersome and unattractive.

At present, some embedded development learning boards adopt the design form of core board and backplane, and the backplane is also integrated with as many functional modules as possible, but there is still a problem of waste of the board. Scalability and upgrade and update capabilities also have the disadvantages of the board.

At present, some embedded development learning boards adopt the design of the peripheral expansion function board on the above two foundations. The motherboard and the backplane are also integrated with as many functional modules as possible, but there is still a problem of waste of the single board. Although the motherboard has an extended interface to the outside, this interface corresponds to a specific function board. If it is replaced with another function board, it will not work. This interface is only for the user to select and not select this function. The use of the board, obviously such scalability is very poor. Moreover, the modules thus expanded are inserted horizontally around the motherboard, or vertically inserted on the motherboard, which is not beautiful. To expand, upgrade, and replace a function module that does not have an existing interface, there is also the disadvantage of a single board.

Summary of the invention

Based on this, it is necessary to provide a development board structure in which various functional modules can be placed, and each development board structure can be spliced and fixed to each other and electrically connected.

In addition, a circuit system based on the structure of the development board is also provided.

A development board structure comprising a board having a standard size and a power connector and a connecting portion disposed on the board; the board is used for placing a circuit function module; the power connector is used for development Electrical connection between the board structures, the development board structure and the power source, and also electrically connected to the circuit function module; the connection portion is used to develop a fixed splicing between the board structures; the board body is square, and The standard size belongs to the following set of sizes: {length mx, width ny, m≥1, n≥1 and is a positive integer}, where x, y are fixed lengths.

A circuit system comprising a plurality of circuit components, each circuit component comprising the above-mentioned development board structure and a circuit function module formed on the development board structure; wherein each circuit assembly adopts a board structure of a development board structure The standard size is adapted to the size of the circuit function module; the plurality of circuit components form a power supply path through interconnection between the power connectors, and/or through a connection between the power supply auxiliary connector and the power connector The plurality of circuit components form a fixed splicing by a fixed connection between the fixing member and the connecting portion on the board body.

The above circuit system adopts the above-mentioned standard size development board structure, and the function module can be set on the development board structure. Multiple development board structures can be freely spliced directly to each other, and can be easily added, removed, and changed, so the assembly of the circuit system is more flexible.
