[Jike Laobai] How to learn schematic design? Do I need to learn to design schematics when working with development boards like stm32?

1. How to learn the schematic design?
Teacher Bai Jilong's answer: First of all, you must be familiar with most electronic components, and you can understand most types of electronic circuits. After that, you can refer to the company's design and completion at the beginning. Modify the company’s needs little by little, understand each function, and wait for you to learn some basic routines from others, and then start to learn how other people’s design ideas are, and learn the design thinking mode. Almost if the company has a new project, it can start to try independent design schematics.

2. Do I need to learn to design schematics when working with development boards like stm32?
Teacher Bai Jilong's answer: The development board can only be said to have realized the primary schematic design of the function. The real schematic design should be designed from the perspective of the product. The interface part needs to consider safety regulations, static electricity, etc., how to reduce the EMC of the product in the schematic diagram, whether the power inlet should remove common mode interference, reliability, and cost , The schematic revision after the failure analysis, etc. can ensure that the schematic design is qualified. Of course, some new products do not have any schematics to refer to. At this time, you need to design the schematics independently. Routines and design thinking are difficult to build a good, stable, reliable, and cost-effective product!
