What is a Servo Drive?16 June 2021
Servo drive, also known as "servo controller" and "servo amplifier", is a kind of controller used to control servo motors. Its function is similar to that of frequency converters acting on ordinary AC motors, and it is part of the servo system. The servo drive is mainly used in high-precision positioning systems. Generally, the servo motor is controlled by three methods of position, speed, and torque to achieve high-precision transmission system positioning.
MEMS Basics: System Features and Classifications11 June 2021
MEMS, also called micro-electro-mechanical system or micro-system, refers to high-tech devices with dimensions of a few millimeters or even smaller. The internal structure of MEMS is generally on the order of micrometers or even nanometers. A micro-electromechanical system is a micro-device or system that integrates micro-sensor, micro-actuator, micro-mechanical structure, micro-power supply, micro-energy, signal processing and control circuit, high-performance electronic integrated device, interface, and communication.
How Fast is Wi-Fi 6?07 June 2021
Wi-Fi 6 ( IEEE 802.11.ax) is the sixth-generation wireless network technology and the name of the Wi-Fi standard. It is a wireless local area network technology created by the Wi-Fi Alliance based on the IEEE 802.11 standard. Wi-Fi 6 will allow communication with up to 8 devices with a maximum rate of 9.6Gbps.
What is UWB (Ultra-wideband)?04 June 2021
UWB (Ultra-wideband) technology is a wireless carrier communication technology, which does not use a sinusoidal carrier, but uses the non-sinusoidal narrow pulse of the nanosecond level, so the spectrum range is wide.
VRAM (Video RAM) Explained03 June 2021
VRAM (video RAM), also known as a frame buffer, is used to store the rendering data processed or about to be extracted by the graphics chip. Like computer memory, VRAM is a component used to store graphics information to be processed.
Bluetooth Explained: Characteristics and Applications02 June 2021
Bluetooth is a global specification of wireless data and voice communication, which is a special close-range wireless technology for setting communication environments for fixed and mobile devices. Bluetooth allows some of the current portable mobile devices and computer devices to connect to the Internet without a cable and can be wirelessly accessing the Internet.
What is a Wireless Network Adapter?01 June 2021
The wireless network adapter is actually a terminal wireless network device, which needs to be used for Internet access through the wireless connection network under the wireless coverage of the wireless local area network. With a wireless network adapter, it also needs a wireless network that can be connected, so it needs to be used with a wireless router or wireless AP.
What is a Hard Disk Drive (HDD)?31 May 2021
Hard Disk Drive (HDD) is the main storage device of a computer. It consists of one or more aluminum or glass discs. These discs are covered with ferromagnetic material. The vast majority of hard drives are fixed hard drives, which are permanently sealed and fixed in the hard drive. With the development of hard disk drives, removable hard disk drives have also appeared, and they are becoming more and more popular.
What is Universal Serial Bus (USB)?28 May 2021
Universal Serial Bus (USB) is a serial bus standard and a technical specification for input and output interfaces. It is widely used in information communication devices. The latest generation is USB4, and its transmission speed is 40Gbit/s, the three-stage voltage is 5V/12V/20V, the maximum power supply is 100W.
Graphics Card Explained: Classification, Working and Structure27 May 2021
A Graphics card (Video card, Display card, Video adapter) is one of the basic components of personal computers. It converts the display information required by the computer system to drive the display, which is an important component that connects the monitor and the PC motherboard, and is one of the important equipment of "human-machine". Its built-in parallel computing capability is also used for deep learning and other operations.
Wireless Charging Explained: Working and Standards26 May 2021
Wireless charging technology originates from wireless power transmission technology, which can be divided into low-power wireless charging and high-power wireless charging. Low-power wireless charging often uses electromagnetic induction, such as the Qi method for charging mobile phones. High-power wireless charging often uses resonance (most electric vehicle charging uses this method) from the power supply equipment (charger) to transfer energy to the device that uses electricity.
What is a USB Flash Drive?25 May 2021
USB Flash Drive integrates disk storage technology, flash memory technology, and universal serial bus technology. The USB port is connected to the computer, which is the channel for data input/output. The master chip makes the computer identify the USB flash drive as a movable disk, which is the "brain" of the USB flash drive. The flash memory saves data. The PCB bottom plate connects the components together and provides a platform for data processing.
