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 4 versions: A, A+,

December 16, 2017Micro: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,

December 11, 2017Voice 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

November 01, 20171.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, the

September 28, 20171. The overlap of the welding plates. a. The overlap of welding plates means the holes are overlapped, when multiple drilling happens to one position, it would result in the damage of hole. b. Overlap of two holes in a multi-layer board will cause it scrapped. 2. The abuse of graphics layer. a. Doing some useless connection in the graphics layer is easily misunderstood, for example, a design for 4 layer PCB uses the circuit of 5 layer PCB or even above. b. In violation of conventional design, such as, the side of electronic parts is designed at the Bottom layer, and the welding side is designed at the Top layer, these all will cause troubles. 3. The characters are in a mess.

August 17, 2017Panelizing is common used in the PCB board’s production for it can get more value in a low cost. For some customers, the size of single boards can’t properly used on their project so they need a bigger size. That’s the main reason for customer choose panelizing service, here is an introduction of panelizing service of Elecrow. We have two ways of panelizing, one is V-cut and the other is snap off holes. For V-cut, the minimum size of board is 8*8cm. V-cut is a straight and uninterrupted line, the mini spacing between 2 V-cut line is 2mm, and different thickness has different request. For 1.6mm thickness boards, V-cut line must has 1mm spacing with the edge of boards; for 1.0mm thickness should be 0.7mm. Customer can add the V-cut line in the GKO layer or the silkscreen

There are a lot of products sell on Tindie and cooperated with Elecrow. Here I would like to recommend several tindie top seller products. The first seller is Raj, the owner of Embedded Lab Store. The designer Raj cooperate with Elecrow since 2013 and we have a wonderful cooperation. And a big thanks that Raj recommend us on his blog at the end of last year. The Easy Pulse is a DIY pulse sensor that is designed for hobbyist and educational applications to illustrate the principle of photoplethysmography (PPG) as a non-invasive technique for detecting the cardio-vascular pulse wave is that we used the DS202-
