PCB Modular Layout Approach In the face of increasingly integrated hardware platforms and complex electronic products, PCB layout should adopt a modular mindset, requiring modular and structured design methods in both hardware schematic design and PCB routing.As a hardware engineer, under the premise of understanding the overall system architecture, one should consciously integrate modular design … Read more
The ground plane and power plane are large conductive areas in PCB design with various purposes. The ground plane provides a common reference point for electrical signals and serves as a return path for current. The power plane transmits power voltage to various components on the circuit board, helping to evenly distribute power across the … Read more
I am Lao Wen, an embedded engineer who loves learning.Follow me to become even better together!As an amateur embedded engineer, my main job involves using microcontrollers to detect button actions and implement various LED light effects (advanced lighting). Occasionally, I also design simple circuit boards and solder some smart hardware to validate ideas or technical … Read more
MIPI (Mobile Industry Processor Interface) is a core transmission standard for devices such as smartphones, tablets, and automotive systems, which includesD-PHY (used for CSI cameras/DSI displays) andC-PHY (higher bandwidth, no independent clock) physical layer protocols. Its characteristics include: Differential Signals: D-PHY includes 1 pair of clock + 1~4 pairs of data lines; C-PHY transmits embedded … Read more

Is it possible not to place silkscreen position numbers on a PCB? The silkscreen position number is mainly for convenience during manual soldering or prototype debugging stages, as it visually indicates the component positions, facilitating assembly, maintenance, and testing, primarily used in the prototype phase. It is indeed possible to manage without position numbers when … Read more
1. Determine the Scheme and Purpose Hello everyone, today I will introduce the LHA7668 chip from the F4 series development board, which is a domestic, 24-bit, 8-channel differential, and 16-channel single-ended high-precision low-power ADC chip. The goal is to design a circuit board to meet the requirements for 16-channel single-ended acquisition or 8-channel differential acquisition.The … Read more
In the process of PCB layout and routing, it is crucial to follow certain design guidelines to ensure the stability and reliability of the circuit. Below are 20 essential PCB layout design guidelines that we hope will be helpful to everyone. 1. Isolation of Strong and Weak Currents, High and Low Voltages, and High and … Read more
As I walk along the waves, occasionally looking back, though I cannot see the marks, I can still glimpse the distant shore. Since graduating in 2015, it has been eight years. I have worked in hardware for eight years, and my love for it runs deep. I still remember a friend I met in the … Read more
