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

June 22, 2017Regular PCB boards produced by Elecrow are based on class 2 of IPC-600-H (Acceptability of PCB). Click here to check and download the industry standards IPC-600-H. Definition for Rush Service:
- The timestamp on your order of the 12h rush service must be before 2PM Beijing Time to qualify. An order placed at 2PM and later will be considered to the next business day. Similarly, the 24h rush service will be put off the next business day when the order is placed at 6PM or later. The time used is the timestamp on your order, which will be showed once your order is placed. Besides, the 12h rush service is not included stencil and ENIG technology. But the ENIG is available in the

June 14, 2017PCB Sculpture is quite popular items in circuit board art. Circuit board is not only an important basic of the online lives in the 21st century, but also a works of art. Similarly, PCB designer was a technician of the PCB layout as well as an artist. Maybe we could collect and re-use the obsolete and spare PCBs, to protect environment and change the waste into resource. You may have seen the artwork which made of the PCBs by Steven:

The application prospect of pcb is very vast, you can applied it to the arduino/raspberry pi projects or assembled some chips into its surfaces etc. Here we share a project where I saw in the instructable.com that diy an arduino robot. It is a simple robot which is operated by an arduino and what it does is that it just roams around and avoids obstacles. 1. Materials Required
2. Wiring and Schematic

May 22, 2017PCB board is also known as printed circuit-board, which plays an important role in the electronic parts. Thanks to its special advantages that combines density, high-reliability, assemble and maintenance, which makes it been widely applied in the electronic industry. What are you most concerned about the aspects of PCB fabrication? Is quality, price or service? I believe that the price is the primary concerned for most customers. Then do you know how to estimate the cost of PCB board? The cost of the PCB board can be affected by many things including the material, technology, surface treatments and quality assurance test, etc. PCB can be divided into three classes from its material: fiberglass panels (FR-4),

May 15, 2017Raspberry Pi is also known as single-board computer, which is based on an ARM microcomputer motherboard and its size is similar to credit card, but it with all the basic functions of the computer. Since its advent, it has a lot of fans who is maker and computer enthusiasts. Although it looks small, its heart is very strong. If you want to learn more about raspberry pi functions and interface types etc, you can refer to the wiki. There are a lot of the makers sharing their raspberry pi projects on the instructable. For most of the maker, the raspberry pi screen is they will buy the goods. It can be applied to various occasions to achieve the data presentation function. In addition to raspberry pi official screen, the following screens can also be applied to

The image is mainly about the difference between the work principle of WS2812 and WS2813 LED strip. The most obvious difference is: when the led one of the WS2812 was broken, it will affect the other led working, but the WS2813 will not appear above situation.
If you don’t know the WS2812 or WS2813, please allow me to introduce them to you.
Generally speaking, WS2812 has two versions: WS2812 and WS2812B. WS2812B is an upgraded version of WS2812. They are an integrating control circuit and the intelligent external control LED source of the light-emitting circuit, which looks similar to the 5050LED. It internal included intelligent digital port data latch and signal reshaping amplification drive circuit. Also include a precision internal

February 24, 2017STEM is a curriculum based on the idea of educating students in four specific disciplines — science, technology, engineering and mathematics — in an interdisciplinary and applied approach. "The future of the economy is in STEM." And it's is so important for our children, our region and our country, we need to encourage the students currently in our educational systems, as well as future generations of students, to understand and embrace the technology that affects them every day of their lives.
And in this article, I will introduce you the top 5 most funded STEM kits on Kickstarter.
