difference impedance) should remain unchanged, that is, to maintain parallelism. There are two parallel methods: one is to walk two lines in the same side-by-side layer, and the other is to walk two lines in the upper and lower adjacent two layers (over-under ). In general, there are many ways to implement side-by-side. The difference wiring must be the signal source and the receiver are also the difference signal to make sense. Therefore, differential cabling cannot be used for clock signals w

development. Although our open-source list usually focuses on software, this list also contains some open-source hardware, most of which are offered to IOT enthusiasts at a low price. As usual, If you think some projects should appear on our list, please don't hesitate to give us some advice and write these projects in the comments section below. Development Tools 1. Arduino Arduino contains an interactive electronic hardware specification and a set of software. This software includes IDE and

Each saw is charged for the length of the current wood board. The minimum cost is calculated based on the length of each sub-board and the number n of sub-boards. Tip: To 3 5 8 5 For example: First saw a 21-length

has the following eight features to meet the needs of large-scale IP networks for multiple businesses, high reliability, large capacity, and modularization. 1. advanced architecture Quidway S8500 series products adopt a fully distributed architecture design. They use powerful ASIC chips for high-speed route searches and use Crossbar Technology for High-Speed Packet Exchange, this greatly improves the forwarding performance and scalability of 10-gb core switches.

public impedance between them, and its impedance coupling is restrained. The local decoupling capacitor is installed between the power terminal and the ground terminal of each integration piece, and is as close as possible to the Integration piece. The decoupling capacitor between the Board refers to the capacitance between the power supply plane and the ground plane. It is the main source of decoupling current at high frequencies. The Inter-board capacitor can be increased by adding the area b

conditions and methods, therefore, both parties will clearly define the following items: 1. Test Data Source and format 2. Test conditions, such as voltage, current, insulation and connectivity 3. device production method and selection 4. Test chapter 5. Patch specifications In the PCB Manufacturing Process, there are three phases that must be tested: 1. inner layer after Etching 2. After the outer line is Etching 3. Finished Products Each stage usually has 2 ~ 3 tests of 100%, filtering out ba

Fence rails Burch, kolstad, and schrijvers Farmer John is trying to erect a fence und part of his field. he has decided on the shape of the fence and has even already installed the posts, but he's having a problem with the rails. the local lumber store has dropped off boards of varying lengths; Farmer John must create as much of the rails he needs from the supplied boards. Of course, Farmer John can cut

thick, as long as the time is extended, suitable for bonding boards. the chances of e-gold potion waste are smaller than that of gold. however, the electric Fund requires full-board conduction, and is not suitable for very small lines. gold is usually very thin (less than 0.2 microns), the purity of gold is low. work fluid can only be discarded to a certain extent The circuit board of a gold board has the following features: 1. the scalability of the

can see the essence through the floating cloud. dm9000 is a network device and should naturally have a structure related to this network device. How can we define it? You don't have to worry about it, because the Linux kernel has already been defined for us and can be used directly. It is struct net_device, so we know that although it is also a network card, however, they may be connected to different boards, such as Samsung

As long as you do business, you will earn money. Note:1. I had this idea mainly because I recently sold several circuit boards and made several hundred yuan of quick money. I found that the money was too easy. I just chatted with people online, although I was not chatting with others, but they gave me money. 2. the major significance of doing business is to boldly open your pockets so that money can flow in easily. The truth is that if you don't tell

For embedded learning, we often have to deal with uboot and kernel,Source insightThat is, I think it is a very good source code viewing tool. For Viewing uboot and kernel source code, it has a very good indexing method and a very convenient shortcut key operation method. It is best to build a project to manage a huge source code tree. However, when you search for a keyword, many related files will appear, and different CPUs and boards will have files
