The development of modern electronic industry is changing rapidly, with large-scale and ultra-large-scale integrated circuits becoming increasingly complex. The traditional method of manually designing and manufacturing circuit boards can no longer meet production needs and is prone to errors. Here, I will introduce how to automatically convert schematics into PCB layouts. By relying on the … Read more
In the process of hardware circuit design, mistakes are inevitable. Have you made any rookie errors? The comment section is open for you. Below are the five most common design issues in PCB design along with their respective countermeasures. 01 Pin Errors Linear voltage regulators are cheaper than switching power supplies but have lower energy … Read more
When designing a PCB, I found that many people, especially beginners, do not have a clear understanding of the layers in a PCB. Therefore, today let’s take a look at the differences between the various layers when using the software Altium Designer to create a board. 1. Signal Layer The signal layer is divided into … Read more

The abbreviation for printed circuit board: PCB 3. The main functions of printed circuit boards: Supporting circuit components and interconnecting circuit components, namely the two main roles of support … Read more
Figure 1 Experimental Scene Recently, the author has been using Phyphox and ESP32 to capture the current changes when a light bulb is turned on. However, the current change at the moment the light bulb is turned on is quite rapid, making it difficult to draw an ideal current change graph. WeChat Official Account “Physics … Read more
In this digital age, computer technology has become indispensable in every aspect of our lives. Whether it’s smartphones, smart homes, self-driving cars, or artificial intelligence, computer technology plays a crucial role. So, what are the divisions within computer majors? What do EE, CE, CS, SE, CIS, MIS, and IT stand for? How should students choose … Read more
I2C is a two-wire serial communication bus, consisting of an SCL signal and an SDA signal. SCL is the clock signal sent from the master device, while SDA is the data signal, which is bidirectional, allowing devices to send and receive data through the SDA signal. When designing the I2C signal circuit, we add a … Read more
I2C is a common serial communication interface, which is available on most processors. The I2C interface is an open-drain structure, so pull-up resistors are needed in the design to drive the high level. As shown below: Rp is the pull-up resistor, and the dashed box contains the internal I2C controller structure of the chip (for … Read more
