The construction of component packaging is an important part of PCB design. A small mistake can lead to the entire board failing to work and serious delays in the project.Most CAD tools come with a built-in library for standard component packaging, which can also be obtained from the manufacturer’s design documents and reference design sources. … Read more
The following content is a collection of knowledge and techniques I have gained from recently soldering surface mount components, which I am now selflessly sharing with you (if you can understand it, then great! ~ (～￣▽￣)～). However, I want you to know that soldering is not something you can learn in just a few tries; … Read more
PCB Layout is a meticulous task that involves not only regulatory constraints but also numerous details that engineers need to consider. In this article, we have compiled some critical details to pay attention to in layout design. Let’s see if you are aware of them! 1. Layout of Special Components √ Heat-generating components should be … Read more
Many people who have learned STM32 share a common characteristic: they can only use some representative hardware features, such as AD conversion, and can only perform single conversions, while they do not know how to perform loop or multiple conversions. Then they have to refer to the chip manual, but the problem is that the … Read more

Sensors are devices or instruments that can sense specified measured quantities and convert them into usable output signals according to certain rules. In modern industrial production, especially in automation processes, various sensors are used to monitor and control various parameters in the production process, ensuring that equipment operates in a normal or optimal state and … Read more
01 Why Understand Chips The popularity of mobile phones, especially smartphones, is actually a phenomenon of the last decade or so. Now our phones have become a small world that immerses people, all thanks to mobile phone chips. Inside every phone, there are small chips constantly executing various instructions. This relies on many semiconductor components … Read more
What Are Semiconductors When electric current passes through various objects, different objects have different capacities to impede the flow of current. Some objects allow current to flow smoothly, while others do not allow it to pass or do so with certain resistance. This varying ability of objects to conduct electric current is called their conductivity. … Read more
In our daily work and life, we often use various electronic or electrical products, such as computers, mobile phones, televisions, refrigerators, washing machines, etc.These products, if we take them apart, will reveal a green board like the one below.Sometimes it may be blue or black.Everyone knows that this green board is called a circuit board. … Read more
Many electronic products have status indicator lights, such as TVs: Standby state lights upred light Power on state lights upgreen light It is very simple to implement, just control two GPIOs of the microcontroller (MCU): However, resources are always tight, and sometimes you may encounter situations where there are not enough GPIOs.If only using 1 … Read more
