Hello everyone~ It’s time for another weekly review information, come and learn about the new review developments!Newly launched development board activities and activities that have reopened the eval...
Today's 7nm EUV chips have more than 10 billion transistors. How are they installed?Transistors are not installed. Chip manufacturing is actually divided into processes such as sand-wafer and wafer-ch...
We were originally planning to use a 4.3-inch touch screen to display the real-time results, but due to some problems, we could only use a host computer so that the progress could be faster.
The inter...
Overall system design 1) The controller of this design uses 51 single-chip microcomputer 2) ADC0808 collects the voltage division of the photoresistor The weaker the light intensity, the more LEDs wi...[Details]
In power systems, MOSFET drivers are generally used only to convert the output signal of the PWM control IC into a high-speed, high-current signal to turn the MOSFET on and off at the fastest speed. ...[Details]
1 Introduction
DC motors have good starting and braking performance and are suitable for smooth speed regulation in a wide range. They have a long history of application in fields that requir...[Details]
The biggest advantage of 4K is its high resolution. However, video surveillance is a system. 4K has brought higher requirements for transmission, storage, and intelligent analysis, and requires relev...[Details]

TWS (True Wireless Stereo) Bluetooth headsets are extremely popular audio products in recent years. With the help of Bluetooth chips, it first establishes a wireless connection between the mobile pho...[Details]
Tesla and PG&E recently broke ground on a record-breaking energy storage system in Moss Landing, California, which, once completed, will be the largest energy storage installation in th...[Details]
(II) ADC cyclically collects six voltages, using DMA. This experiment was really depressing. My lack of understanding of DMA made me fall into misunderstandings. After understanding it, I admire...[Details]
Many people have seen the movie where a computer expert can control a bunch of cars with just a few tinkerings, and make them go wherever they want. After watching the movie, while feeling very excit...[Details]
The AP3103 is a low start-up current, current-mode
PWM controller with green-mode power-saving
operation. The PWM switching frequency at normal
operation is externally programmable and is ...[Details]
