The Difference and Application of SPI, UART, I2C Communication15 October 2025
Hello everyone, I am Rose. Welcome to the new post today. Communication between electronic devices is like communication between humans. Both parties need to speak the same language. In electronic products, these languages are called communication protocols. This article will make some comparisons between SPI, UART, and I2C.
LDO VS DC to DC Converter11 March 2022
Hello everyone, I am Rose. Today I will introduce the differences between LDO and DC to DC Converter to you. LDO stands for low dropout regulator, which is a low dropout linear regulator.A DC/DC converter is a voltage converter that converts an input voltage and efficiently outputs a fixed voltage.
Circuit Breaker: Working Principle, Types and Structure21 November 2025
Circuit breaker is a switching device capable of closing, carrying and breaking the current under normal and abnormal circuit conditions within a specified time. So what's its structure and how many types are there? How does it work? Read this.
What is a Thyristor?11 December 2020
Thyristor, also known as silicon controlled rectifier (SCR), can control its conduction through a signal, but cannot control its turn-off, so it is called a semi-controlled device. The name thyristor often refers specifically to a basic type of thyristor, but broadly speaking, thyristors also include many derivative devices, such as Tri-Electrode AC switch (TRIAC), Fast Switching Thyristor (FST), Reverse-Conducting Thyristor (RCT) and Light-Triggered Thyristor (LTT).
What is an Inverting Amplifier?25 April 2025
An inverting amplifier is a fundamental configuration of operational amplifiers where the output signal has opposite polarity to the input signal. This configuration uses an operational amplifier with its inverting input terminal receiving the input signal, while the non-inverting terminal is typically connected to ground. The primary function of this circuit is to amplify the input signal while inverting its phase by 180 degrees.
What are Wire Wound Resistors?19 January 2026
Wire wound resistors are a type of fixed resistors. Wire-wound resistors are constructed with resistance wires wound on an insulating frame. The resistance wire is generally made of nickel-chromium, manganese-copper alloys with a certain resistivity.
Shift Register: Classification and Working Principle26 December 2020
The shift register is a sequential logic circuit that can be used to store or transmit data in the form of binary numbers. It loads the input data and then moves or "shifts" it to its output every clock cycle, so it is called a shift register.
Toggle Switches: Features, Types and Applications23 January 2021
Toggle switch adopts integrated circuit technology and SMT appearance device technology to manufacture a new generation of photoelectric switch devices. It has intelligent functions such as delay, expansion, external synchronization, anti-interference, high reliability, stable working area, and self-diagnosis. This novel photoelectric switch is an active photoelectric detection system electronic switch that uses pulse modulation. The cold light source used is infrared light, red light, green light and blue light, etc., which can be quickly and without contact and damage Control the state and action of various solid, liquid, transparent, black, soft, smoke and other substances.
Resistor Symbols: From Circuit Diagrams to PCB Design08 August 2025
This comprehensive guide explores resistor symbols used in electronic circuit diagrams, covering the two main international standards: IEC (rectangle symbol) and ANSI (zig-zag symbol). The article explains how to read and interpret these symbols in schematics, distinguishing between fixed and variable resistors, and detailing specialized types like thermistors, LDRs, and varistors. It provides practical guidance for locating resistor symbols in popular EDA software (KiCad and Eagle) and includes a downloadable reference chart. The guide serves as an essential resource for electronics enthusiasts, students, and professionals who need to understand the universal language of electronic schematic symbols for circuit analysis, design, and troubleshooting.
Why is 50 ohms?13 June 2022
Hello everyone, I am Rose.Welcome to the new post today. Today We will discuss why impedance is 50ohm, not 30ohm, 75ohm or 100ohm?
An Overview of SD Card12 April 2021
The SD (Secure Digital) card is a new generation of memory devices based on semiconductor flash memory. Due to its small size, data transmission speed, hot-swap, and other excellent features, it is widely used in portable devices, such as digital cameras, tablets, and multimedia players, etc.
