Serial interfaces are primarily used for serial bit-by-bit data transmission, allowing for bidirectional communication with just a pair of transmission lines, which offers the advantages of simple communication lines and low costs. Nowadays, many serial data interfaces are used in specific fields, with common examples including I2C, CAN, LIN, SPI, Flex, MOST, and I2S. Of … Read more
As a newcomer to the field of wireless modules, there are certainly some unclear aspects regarding the role and application scenarios of WiFi modules. In this article, I will explain the role and application scenarios of serial WiFi modules. WiFi Module 1. Definition: The serial WiFi module is a widely used wireless communication module that … Read more
Bluetooth communication is quite interesting! In simple terms, it allows microcontrollers to chat with mobile phones and communicate with tablets. Beginners often find this quite challenging, but really… it’s just a serial port! Today, we will start from the basics and break down these seemingly advanced technologies. Basic Concepts – Don’t Be Intimidated by Terminology … Read more
UART, or Universal Asynchronous Receiver/Transmitter, is one of the most commonly used communication protocols between devices. When configured correctly, UART can work with many different types of serial protocols that involve sending and receiving serial data. In serial communication, data is transmitted bit by bit over a single line or wire. In bidirectional communication, we … Read more
Hello everyone, I am Da Yi, and today we are going to talk about the serial communication protocol between microcontrollers (MCU) and PLCs. When it comes to serial communication, many of you might feel confused, but don’t worry, I will clarify everything shortly. What is Serial Communication?Communication is everywhere; for example, the way you and … Read more
Click the Blue Word Follow Us UART (Universal Asynchronous Receiver/Transmitter) is a widely used serial communication protocol, typically used for communication between computers and peripherals. It is a general-purpose serial, asynchronous communication bus with two data lines that enable full-duplex transmission and reception. UART is a serial communication protocol that transmits data bytes bit by … Read more

(Click the red text above to get the materials for free) RS-232, RS-422, and RS-485 are serial data interface standards. RS-232 is the most widely used serial interface for PCs. It is defined as a single-ended standard for increasing communication distance … Read more
RS-232 is a serial data communication interface standard established by the Electronic Industries Alliance (EIA) in the United States, originally designated as EIA-RS-232 (commonly referred to as 232, RS232). It is widely used for connecting computer serial interface peripherals. The RS-232C standard, where EIA (Electronic Industry Association) represents the Electronic Industries Alliance of the United … Read more
Click the blue text to follow Servo and Motion Control RS232 and RS485 are common interfaces in low-voltage electronics. Many friends have mentioned the differences between them, so today let’s explore them together. 1. Physical Structure of the Interface 1. RS232 Interface: RS-232 uses an unbalanced transmission method, known as single-ended communication. In contrast, RS485 … Read more
Introduction to RS-232 Serial Port Data transmission between computers or between a computer and a terminal typically employs two methods: serial communication and parallel communication. Serial communication is widely adopted due to its lower cost and fewer lines used, especially in remote transmission, which avoids inconsistencies caused by multiple lines. In serial communication, both parties … Read more
