The red and blue two-color dot matrix control circuit uses 4 573s to drive the rows and 16 transistors to control the columns. How big a current limiting resistor should be used at the output end to e...
Currently, the share of medium and high voltage inverters in the total inverter sales has increased to more than 15 %. Do you think this means that the overall sales peak season for medium and high vo...
Why can't the driver be installed on Win7 64 bit? And the recognized name is not correct. I tried it on my classmate's Win7 32 bit and there was no problem......
Introduction to the principles of speech recognition technology
Automatic speech recognition (ASR) technology aims to enable computers to understand human speech and extract the textual inform...[Details]
The difference between a series inverter and a parallel inverter is that they use different oscillation circuits. A series inverter connects L, R, and C in series, while a parallel inverter connect...[Details]
We often hear about the precautions for using pure electric vehicles in winter, and many owners even develop relevant strategies, such as adopting a "charge as you go" principle for their vehicles,...[Details]
Electric vehicles are composed of three main components: electric motors, electric motors, and electric vehicles. Maintenance is much simpler than for gasoline-powered vehicles. Maintenance for ele...[Details]

The Waveshare ESP32-P4-ETH is a compact ESP32-P4 development board with Ethernet and PoE support. It looks very similar to the Olimex ESP32-P4-DevKit, minus the pUEXT connector. However, we've also...[Details]
Today, the voltage of electronic products continues to rise to 400V, 600V and even 1000V, so there are few electronic load models that can handle such high voltages. Many people consider connecting...[Details]
With rapid economic development, the types of pollution sources are increasing, especially in chemical and industrial zones and their surroundings. The patterns of pollution and the types of ecolog...[Details]
Generally not, but there are exceptions. For example, a torque motor controller with three-phase output voltage imbalance can cause current imbalance, similar to a phase loss. However, only two pha...[Details]
Charge your electric car for just six minutes and you'll get 1,000 kilometers! This isn't just a scene from a science fiction film, but a reality made possible by Guoxuan High-Tech's Jinshi solid-s...[Details]
EVTank predicts that all-solid-state batteries will achieve small-scale mass production in 2027 and large-scale shipments by 2030. Global solid-state battery shipments will reach 614.1GWh, of which...[Details]
