RF (Radio Frequency) and Mixed Signal PCB Layout Guidelines RF (Radio Frequency) and Mixed Signal (Analog & Digital Mixed Signals) PCB design requires special attention to issues such as signal integrity, noise control, and electromagnetic interference (EMI). Their layout differs from ordinary digital PCB design because they involve high-speed signals, the coexistence of sensitive analog … Read more
1. STM32 and Selection 1.1 STM32 vs 51 Microcontroller Both STM32 and 51 are types of small computer chips that allow us to write code and store it within. For example, we can control a pin to switch between 5V and 0V, connecting an LED to this pin to achieve a blinking effect. This operation … Read more
What Is Impedance? Isn’t It The Same As Resistance? Regarding impedance (Impedance), I have found that many newcomers to this concept often confuse it with resistance (Resistance). This confusion may arise because both terms contain the character for “resistance” in Chinese, and both units are expressed in Ω. Additionally, impedance and resistance are related to … Read more
Introduction With the growing demand for networking, the issue of gigabit Ethernet speed has garnered significant attention. This article analyzes the low actual speed situation, detailing reasons such as poor wiring, and provides effective methods for improving speed and stability from both hardware aspects like equal-length wiring and impedance matching, as well as software debugging … Read more
