To develop a Linux driver, you must check the principle diagram and PCB.There are three common practices:1. The host uses the Windows system and installs Linux in virtual machines such as VMWARE so that you can use the software in Windows to view the schematic diagram and

Printed circuit boards (PCB) appear in almost every electronic device. If there are electronic parts in a device, they are all mounted on PCB of different sizes. In addition to fixing all kinds of small parts, the main function of PCB is to provide the electrical connection between the above parts. A

When it comes to PCB, many friends will think of it everywhere around us. From all household appliances, various computer accessories, to various digital products, PCB is almost used as long as it is an electronic product, so what is PCB? PCB is the printedcircuitblock, that is, the printed circuit board, fo
problems, especially the EMC and EMI Problems in High-Speed PCB wiring. There are many conflicts and they are a headache. How can we solve these conflicts?
Answer: 1. Basically, it is right to divide and isolate the modulus/number. It should be noted that the signal line should not be crossed through a separate place (moat), or the returning current path of the power supply and signal should be too large.2. the crystal oscillator is a simulated posit

Design of multilayer PCB at, December 30
Before designing a multi-layer PCB, the designer must first meet the requirements of the circuit scale, circuit board size, and EMC.Determine the structure of the circuit board, that is, the four-layer, six-layer, or more layers of the circuit board. After determining the number of layersDeter
