It is well known that PCB design always has a series of principles to follow. If these principles are not adhered to, it may lower the success probability of PCB design, affect product performance, and even have negative impacts on signal integrity, electromagnetic radiation control, and system reliability. Today, this article will analyze these principles, … Read more
Click on the top“Mechanical and Electronic Engineering Technology”to follow us PCB, or Printed Circuit Board, is an indispensable component of modern electronic devices. It acts like a bridge, connecting various electronic components and ensuring that current and signals can be transmitted smoothly. PCB routing is a key part of building this bridge, directly affecting the … Read more
PCB Printed Circuit Board Main Points 01 What is PCB? PCB (Printed Circuit Board) refers to a printed board that forms connections between points and prints components on a common substrate according to a predetermined design. It serves as a support for electronic components and as a carrier for their electrical interconnections. Classification 1. According … Read more
With the development of the automotive industry, the number of electronic control systems in vehicles has grown exponentially. The in-vehicle electronic control system, centered around the ECU, is gradually replacing passive devices and mechanical systems, while also fulfilling most measurement, drive, and control functions. The increase in new in-vehicle electronic control systems in vehicle applications … Read more
1 Introduction After conducting the experiment “Plotting the P-R Characteristic Curve of the Power Supply,” using the existing circuit and making a few modifications to the experimental source code, the microcontroller successfully performed the experiment “Plotting the Relationship Curve between Power Supply Output Voltage and External Resistance.” 2 Circuit Setup for the Experiment Connect a … Read more
Overall Scheme Design Overall Structure Design The wheel-leg robot (LeTian-robot2) utilizes a linkage mechanism (see Figure 1), with the linkage controlled by servos. By controlling the servos on both sides, the overall tilt and lift of the body can be achieved. The feet are directly driven by a 4010 brushless motor without any reduction gear. … Read more
1. Circuit Completion Plan In the previous chapter, we identified the circuit modules required for the smart faucet. Next, we will determine how these circuit modules connect to form a complete “system”. Since our system structure is simple and the components are relatively few, it can be roughly divided into three parts: • Power supply … Read more
Before we begin: 1. This article will focus on Microchip’s products. I believe Microchip has the most articles on clocks among MCU companies. The terminology used by Microchip may differ from that of other companies, but the usage is the same and does not affect understanding. 2. The term “clock source” is used to distinguish … Read more
First, let us briefly introduce the specific functions of each pin of the 51 microcontroller, and then we will focus on the concept of the microcontroller minimal system, its composition, and the practical uses of the circuit diagrams of its various parts. According to the pin identification method of integrated circuits, with the notch facing … Read more
Today we analyze a classic microcontroller power supply circuit, the schematic diagram of the circuit is shown below: ▲ Simplified switch circuit Before powering the circuit, the switch “TEST” is open, and the microcontroller is not powered through VCC. At this point, the base of T1 is grounded through R9 (100k), putting it in the … Read more
