Living in this new digital age, children coming out from schools more need to become makers or inventors creating their own ideas and creating incredible technology to build a bright future. The BBC micro:bit was designed to encourage children to get actively involved in the computer education and make new things, rather than just being consumers of technology. So, let’s see how to develop the skills of making with this tiny computer which costs less than $15 - which means, anyone can have a micro:bit!
From writing code to sharing your creations, micro:bit is the great way to get kids stepped on the maker journey. Here is a recommended route that will make your kids’ experience as smooth and fun as possible.
With years of experience in open source hardware industry and located in Shenzhen which is referred as the largest electronic market of China, Elecrow has developed a mature supply chain in PCB service and wins a good reputation in international electronics hardware communities. Due to the continuous research and concentration on the needs of industry and individual maker, engineer and entrepreneur, Elecrow got down to expand the production lines in 2017 and launched the brand new one-stop solution to hardware project in March, 2018, to be an accessible and cost-effective manufacturing resource for everybody who has ideas to create electronic hardware.
What is one-stop solution to hardware project?
It means our service covers the entire process of building and bringing
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+,
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.

Raspberry Pi touch Screen monitor is widely used by the Raspberry Pi fans. They can make Raspberry Pi tablet, game console, TV display with the Raspberry Pi touch screen.
Raspberry Pi touch screen is one of the hottest items on Elecrow product list, no matter it's on our own store or on Amazon. Let's see what customers used it for and what's their experiences.

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, the
1. 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.
Panelizing 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
Congratulations! We have three new arrivals, they are Solderless Protoboard for Raspberry Pi, Elecrow 11.6 Inch 1920x1080 HDMI 1080P LED Display for Raspberry Pi and SIM5360E 3G Shield.Firstly, the solderless protoboard for Raspberry Pi has a printed circuit board and a single 2*20 GPIO header for raspberry pi toyou’re your Perma-Proto on top of your Raspberry Pi. Almost every pin can be connected to the pin can also be pulled out(Except for #26).It’s very convenient to use this solderless protoboard .You just need to connect it to raspberry Pi, then you can do a variety of experiments on the protoboard.
With the development of the smart phone, the hardware configuration of the phone is continual upgrading that the CPU upgraded from dual-core to ten-core and the RAM now has up to 8GB. The currently new generation of Raspberry Pi is 3B+, which equipped with 1.2GHz, quad-crow and 1GB RAM. In comparison, both based on Linux and adopted ARM architecture, but the configuration of Raspberry Pi 3 is significantly lower than the phone. Why the difference between both so great? Google recently announced a partnership with raspberry pi to launch Raspberry Pi 4. It seems that the configuration of Raspberry Pi 4 should have eight-core, with above 2GHz, with 4GB RAM supported DDR4L. Besides, the Raspberry Pi 2/3B supports the android
