Since the beginning of online shopping, it has brought a huge impact on the traditional real economy in a short period of time. Now in the era of integration of e-commerce and the real economy, traditional retailers need to be more sophisticated in their consumption. And all of this is precisely because of the behind-the-scenes of technology. As a technology at the forefront of big data, cloud computing and artificial intelligence, how much impact will it have on the traditional retail industry? Does it will affect electronic parts industry? In 2016, Alibaba opened its first box in China, hoping to integrate online and offline shopping experiences. Compared with traditional retail, Box Horse uses technologies such as big data, intelligent Internet of things, mobile internet, and automation to achieve optimal matching between people, goods, and fields, from supply chain and warehousing to distribution. Box Horse has a complete logistics system. Now Internet companies are contin

In the 7nm Ruilong 3000 series processor released by AMD, the Ruilong 9 3950X released on the E3 game show is the most eye-catching. The 16-core 32-thread processor itself is not unusual, but the Ruilong 9 3950X is too special. It is the mainstream AM4 platform rather than the previous TR4 platform, still able to achieve 4.7GHz under 16 cores, the official name is called the world's first 16-core game processor. What does it mean to dare to use this statement? DIY players should know that for the CPU, the more the number of cores, the less likely the frequency will be improved. The technology, power consumption, and heat are all limited, so this leads to a very embarrassing problem for the enthusiast processor. Just to prove the top-level identity, their core number is much higher than the average desktop processor, but the consequence is that their frequency is low, resulting in poor game performance. This problem is in Ruilong Threadripper, Intel Core i9 (X299 platform) Ther

Diodes, Inc. (Nasdaq: DIOD) today announced a new line of low-voltage potentiometric converters that enable simple, autonomous bi-directional operation. The PI4GTL2002 is a 2-bit potential converter designed to convert a signal used to regulate a voltage potential to a higher or lower voltage signal, such as converting a Transceiver Transceiver Logic (GTL) or GTL+ to LVTTL/ TTL. As the trend of top processor manufacturers adding GTL+ interfaces to their products continues to rise, the demand for high-performance potential converters in server/data center and network applications is increasing. PI4GTL2002 not only meets this need, but also brings the advantage of not requiring control. The open-drain design of the PI4GTL2002 means that the device can convert voltage potentials from any direction without increasing the design complexity of the dedicated directional control signals, without sacrificing performance. The device is operatively unrestricted and can be converted between 0

The 800V BCM4414 is a 1.6KW isolated, 1/16 fixed ratio bus converter module (BCM®) that operates smoothly from 500V to 800V input voltage and provides SELV output voltage with a peak efficiency of 97%. The new 800V module is a powerful addition to Vicor's existing 700V BCM4414, which creates a range of products with greater isolation (4,242VDC) and bidirectional voltage conversion. The BCM can be easily paralleled into a higher power array, while the SELV output can be stacked (in series) for higher output voltages. Both BCMs are packaged in a 111 x 36 x 9.3 mm VIATM (Vicor Integrated Adapter) package that integrates PMBusTM communication, EMI filtering, and voltage transient protection. VIA's planar form factor package simplifies thermal management and easily interfaces with a variety of different cooling technologies. The BCM can be used for both military (-55 to 100 ° C) applications and communication (-40 to 100 ̊ C) applications. High pressure BCM series Mode

From entry-level to professional, PC-based USB oscilloscopes are becoming more diverse. PC-based oscilloscopes with USB connectivity provide a wide range of performance levels at an affordable price. From entry-level to sampling oscilloscopes with high bandwidth, and new versions that support more features are coming soon. Combining new features, portability and PC processing power, PC-based high-end USB oscilloscopes are beginning to be functionally comparable to desktop oscilloscopes at much lower cost. The PC interface simplifies file processing and editing, making it easy for users to write their own programs to control the oscilloscope. The USB oscilloscope is easy to connect and can be moved at will, almost anytime, anywhere. We have selected seven models from a variety of oscilloscopes, listed in order of cost from low to high. Hantek HT6022BE If you need a small, lightweight, inexpensive entry-level or amateur PC oscilloscope for basic testing, the Hantek HT6022BE wi

1. When using a single power supply, the VEE of the CD4051 can be connected to GND. 2. It is strongly recommended to add pull resistors to the A, B, and C three-chip select terminals. 3. Do not add filter capacitors (parallel to ground) on the common output of CD4051. Otherwise, the voltage after conversion of different channels will cause great error after being discharged by capacitor. 4. When the output terminal (INH) is disabled, all outputs are cut off, so this terminal is grounded when applied. When switching audio signals, it is best to connect a DC blocking capacitor to the input and output terminals. IO port expansion using CD4051 analog switch chip 1, CD4051 introduction For details reference: TI CD4051 Datasheet It can be understood as a single-pole 8-throw switch, the principle is as follows: CD4051 analog switch chip realizes IO port expansion Use three IOs to control the A, B, and C address pins to connect the 3 pins to t
