- An Overview of Bipolar Transistors
27 August 2020
Bipolar Transistor, full name bipolar junction transistor(BJT), is an electronic device with three terminals, made of three parts of semiconductors with different levels of doping. The charge flow in the transistor is mainly due to the diffusion and drift movement of carriers at the PN junction. - ARM, FPGA, DSP and CPLD: Connection and Difference
15 March 2022
Hello everyone, I am Rose. Welcome to the new post today. I am sure you know what is ARM, FPGA, DSP and CPLD. But do you know their connection and difference? Let me introduce to you. - What are the Types of Audio Cables?
27 October 2021
Today, I will introduce you to some common audio cables. I hope you will have a new understanding of the cable of the audio equipment. - Everything You Need to Know about Connectors
07 September 2021
Electrical connectors, as key components for current or signal connections, are also an important part of the industrial system. Connectors can be as huge as airplanes and rockets or as small as mobile phones and televisions, forming bridges between circuits or other components and serving as electric current or signal links. - What is speaker?
08 October 2021
Hi, fellas. Welcome back to the new post today. The speaker is a type of transducer that converts electrical signals to auditory signals. The sound quality is greatly influenced by the speaker's performance. This article introduces some basic knowledge of the speaker. - What is KVM Switch?
05 November 2021
Hello, I am Rose. Welcome back to the new post today. KVM stands for keyboard, video and mouse. The so-called KVM is also called a multi-computer controller, and the official name is a multi-computer switch. A KVM switch is a hardware device that allows users to control 2, 4, 8, 16, or even more than 4096 computer hosts through a set of keyboards, video monitors, and mice. - What is UART(Universal Asynchronous Receiver And Transmitter) ?
25 September 2021
UART stands for Universal Asynchronous Receiver and Transmitter (Universal Asynchronous Receiver and Transmitter). In most embedded devices, it is a communication interface that is set up by default. In this article, I will show you the definition, function, application, working principle, advantage, and disadvantage of it. - What is Brushless DC Motors (BLDC) ?
03 April 2025
Brushless DC (BLDC) motors represent a significant advancement in electric motor technology, combining high efficiency with superior performance characteristics. Unlike their brushed counterparts, BLDC motors eliminate mechanical commutation components in favor of electronic commutation systems, resulting in enhanced reliability and operational longevity. These motors have become increasingly prevalent across various industries due to their excellent torque-to-weight ratio, improved electrical efficiency, and precise control capabilities (Miller & Hendershott, 2022). - Hydrogen Fuel Cell: Features, Working and Applications
21 June 2021
A hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. The basic principle is the reverse reaction of electrolyzed water. Hydrogen and oxygen are supplied to the anode and the cathode respectively. After the hydrogen diffuses out through the anode and reacts with the electrolyte, electrons are released to the cathode through an external load. - Utmel, China's Leading Overseas Component Distributor, at PCIM Europe 2023
