    Top 9 mistakes that PCB engineers need avoid in PCB design

    PCB design is no doubt significant part for creating a PCB board, and also the most difficult process according to some posts in the PCB design forums. Even so, there are some electronics hobbyists and engineers loving doing the PCB designing work by themselves instead of finding a online PCB design service. So if you are one of them, you are gonna have to pay much more attention to these "pitfalls". 1. Unclear specification of processing layer The design of single-sided board should be processed in the top layer. But it could be processed in the front and back sides if without any specification, the board made is likely not to be good for components soldering.

    Differences between Raspberry Pi B, B+, A+, 2B, 3B

    In March 2012, the world’s first card-type Linux microcomputer was launched by Raspberry Pi foundation. Although it’s as small as a credit card in size, it can absolutely work as good as a PC, surfing the Internet, playing 1080P movie and games, editing texts and what’s more, program development are not a big deal for Raspberry Pi. If you are an electronic hobbyist or DIY maker, Raspberry Pi is perfect and the first choice. With some programming knowledge, you can get started with it straight away. In this article, I’m gonna give introductions about each version of Raspberry Pi and their differences, so you can make a right purchase according to your own needs. First Generation of Raspberry Pi The first generation of Raspberry Pi includes

    Sino:bit- The single board microcontroller for computer education in China

    Micro:bit is an ARM-based embedded system designed by the BBC for use in computer education in the UK. The BBC gave away the computer free to every year 7 child in Britain starting from October 2015(around 1 million devices). Micro:bit now becomes a worldwide popular device. The Micro:bit Foundation aims to put the device into the hands of 2 million children in the U.S. & Canada by 2020. "The goal of the micro:bit is to give educators and parents an easy-to-use tool to teach the basics of computer programming and inspire students to imagine, invent and innovate." said Hal Speed, Head of North America at the Micro:bit Foundation. In Japan, the Micro:bit Foundation's goal is to deliver the micro:bit to 300,000 Japanese children by 2020. In Croatia,

    How to voice type and print the text on LCD using Raspberry Pi

    Voice typing feature is quite common to mobile phones; it is considered faster and user-friendly to those who find it difficult to type to input the question about which they need information. If typing fast is required or your handicap, this feature works the best for you. In this article, we will input voice via an Android App and the output will be displayed on LCD using Raspberry Pi. This requires a 16x 2 LCD with Raspberry Pi which is equipped with Bluetooth to receive inputs from the mobile phone. Start with Connecting 16x2 LCD with Raspberry Pi: Setting Bluetooth is preceded by interfacing 16x 2 LCD with Raspberry Pi. Bluetooth setup, first we will interface 16x2 LCD as Raspberry Pi accessory. External

    Difference between single-sided FPC & double-sided FPC & multilayer FPC(flexible PCB)

    All the electronic products have to use PCB to function, so there is a consensus that the trend of PCB market almost indicates the dynamic of the electronic industry. With the development of phone, laptop and PDA and the other advanced, small-sized electronic products like the wearable devices, the demands for flexible printed circuit boards are increasingly growing. PCB manufacturers are focused to create thinner, lighter and higher-density FPC to seize this thriving market. Under the background, I consider it necessary to write about the differences between single-sided flex PCB, double-sided flex PCB and multilayer flex PCB, whether for the PCB fabricators or the open source hardware makers who are likely to buy

    6 elements you need to check in the late PCB design

    When a PCB layout and routing is completed and both the connectivity and spacing are inspected without faults, does it mean the PCB design is succeeded and finished? Of course no. A final inspection is often ignored or neglected by some new engineers, this is likely to result in some bugs or problems in prototyping or even re-prototyping, such as the sockets getting too close, or loop signal and so on. Therefore, a final inspection is a must-do thing of PCB layout. A good final inspection process involves lots of specific steps, here listed some steps that I found quite important but easy to be ignored. 1.Footprint 1). Pads spacing. For the new components, it’s necessary

    How to improve the anti-electromagnetic interference when developing electronic products with processors?

    1.Anti-electromagnetic interference issue should be more careful with the following systems 1)The system that the microcontroller clock frequency is particularly high and the bus cycle is particularly fast. 2)The system contains high-power and high current drive circuit, such as the relay with a spark, high current switch and so on. 3)The system with a weak analog signal circuit and high-precision A / D converter circuit. 2. Measures to improve the anti-electromagnetic interference of system 1)Choose the low-frequency micro-controllers. The use of low external clock frequency micro-controllers can effectively reduce the noise and improve the system's anti-jamming capability. The square wave and sine wave at the same frequency,
