0100-71267 主控板在很多人眼中，主控板有密集的芯片引脚和PCB布线，看起来非常困难。其实恰恰相反,控板的设计有自己独特的设计规律。实上，它就像积木-样。在满足单片机小系统的情况下，需要什么功能只需要增加相关的电路模块，也可以称为模块化设计思路。在本文中，我将从三个层面介绍机器人主控板的设计思路。它们是:基础、设计和原理是主控板基本的部分;科、主控板功能模块扩展及设计思路;籽,计算主控板中功能模块的特定电路参数。我将带您了解使用大树的层次结构作为模型的电路设计的乐趣。基础这里是单片机基础的小系统，是单片机可以正常执行程序的简单工作环境。没有这些，单个芯片将无法运行程序。小系统由电源电路、时钟电路和复位电路组成。大多数芯片都有一个包含所有这三个电路的小系统，而一些芯片不使用外部时钟，可以使用内部RC振荡器为程序运行提供时钟参考。
In the eyes of many people, the main control board has dense chip pins and PCB wiring, which looks very difficult. On the contrary, the design of the dashboard has its own unique design pattern. In fact, it's like a building block. In the case of meeting the requirements of a microcontroller small system, only the relevant circuit modules need to be added, which can also be referred to as modular design ideas. In this article, I will introduce the design ideas of the robot main control board from three levels. They are: the foundation, design, and principles are the basic parts of the main control board; Expansion and design ideas for the functional modules of the main control board; Seed, calculate specific circuit parameters of functional modules in the main control board. I will take you through the fun of using the hierarchical structure of large trees as a model for circuit design. The foundation here is the small system of the microcontroller foundation, which is a simple working environment where the microcontroller can execute programs normally. Without these, a single chip will not be able to run programs. The small system consists of a power circuit, a clock circuit, and a reset circuit. Most chips have a small system that includes all three circuits, while some chips do not use an external clock and can use an internal RC oscillator to provide a clock reference for program operation
