Both core board and development board play an important role in embedded system development, but there is a clear difference between the two. The following is a detailed analysis of the difference between core board and development board:

1. Definition and use

Core board:

Definition: The core board is an electronic motherboard that packages the core functions of MINI PC, integrating key components such as CPU, storage devices and pins.

Use: Mainly used for the core processing part of the embedded system, providing high-performance computing and control capabilities. Connected to the supporting baseboard through pins to achieve the overall function of the system.

Development board:

Definition: The development board is a circuit board used to develop, learn and test embedded systems, which contains the underlying hardware platform on which the system is based and some peripherals.

Use: Mainly used for the initial development, testing and learning of embedded systems. Developers can use the development board to quickly verify the correctness of the system circuit design, write programs and debug.

2. Hardware composition and function

Hardware composition:

Core board: Usually only contains a processor (CPU), memory (such as memory and flash memory), and the most basic peripheral interfaces (such as power supply, clock, etc.). Development board: In addition to the processor and memory, it is also equipped with rich peripheral resources, such as LCD display, keyboard, camera, microphone, Bluetooth module, Wi-Fi module, etc.

Functional differences:

Core board: Focuses on high performance and stability, and provides the core processing functions required by embedded systems. Because of the integration of core components, it has a high degree of integration and versatility.

Development board: In addition to providing core processing functions, it also focuses on ease of use and extensibility. Through the reserved expansion interface and rich peripheral resources, developers can easily develop and test the system.

3. Scope of use and application scenarios

Scope of use:

Core board: It is more used in embedded systems in large-scale production because of its low cost and ability to meet limited peripheral requirements.

Development board: It is mainly used to initially verify the correctness of hardware design and the convenience of software development. It is suitable for beginners to understand and learn the hardware and software of the system.

Application scenarios:

Core board: It is suitable for embedded systems with high performance requirements and high integration, such as smart home, industrial automation, medical equipment and other fields.

Development board: It is suitable for the initial development and testing stages of embedded systems, as well as teaching and research fields.

IV. Summary

To sum up, there are obvious differences between core boards and development boards in terms of definition, hardware composition and functions, scope of use and application scenarios. Core boards focus on high performance and stability, and are suitable for embedded systems in large-scale production; while development boards focus on ease of use and scalability, and are suitable for beginners to understand and learn the hardware and software of the system, as well as the initial development and testing stages of embedded systems. When choosing which board to use, you need to weigh it according to the specific application requirements and development stage.
