What's the microSD card?
MicroSD Card is a very small flash memory card, its format originates from the SanDisk creation, originally this memory card is called T-flash, and renamed to TransFlash, and renamed MicroSD because of the SD Association (SDA) mining. Other memory cards that have been SDA are MINISD and SD cards.
It is mainly used in mobile phones, bu

controller (the component responsible for actual communication) and the security component (the security data area connected to the near-field communication controller) are integrated into the mobile phone itself. An example of a mobile phone that fully integrates near-field communication is the Google Nexus S recently released by Google and Samsung.
Integrated into SIM card:In addition, near-field communication can be integrated into SIM cards, which can identify the cards of mobile phone sub
How to build a practical system on raspberry 3GuideDeploying the openSUSE System on raspberry 3 is not very complicated, but here are some tips to help you better complete this process. You will have some versions to choose from.
If you plan to use Raspberry Pi 3 as a common host, openSUSE with a graphic interface will be your best choice. There are several different graphic environments available: X11, Enlightenment, Xfce, or LXQT. OpenSUSE also has a JeOS version that provides the most basic s

The activity worked very well and was affirmed by all participants. First, Mr. Zhu yongguang (System Architect), a 13-year programming career from Xinbo computer software company, explained his understanding of the development framework, and some of the development frameworks that I have used at ordinary times, combined with C #3.0 to give you a Demo
TF card, also known as microSD, is a very small flash memory card, invented by a famous storage vendor, SanDisk. This card is mainly used in mobile phones, but because it has a small size, with the increased capacity, it slowly began to use in GPS devices, portable music players and some flash memory disk. The TF card insertion Adapter (adapter) can be converted to an SD card, but the SD card is not normally converted to a TF card.

How to select a memory card
The SD card (secure Digital Memory card) is a new generation memory device based on the semiconductor flash memory, which is widely used in portable devices, such as digital camera, personal digital assistant (PDA) and multimedia player. SD Card by Japan Panasonic, Toshiba and the United States SanDisk Company in August 1999 jointly developed. The size is like a stamp SD memory card, weighs only 2 grams, but has the high memory capacity, the fast data transmission ra

Surface RT supports the traditional USB interface, which is indeed very convenient and supports direct insertion of digital cameras and USB flash drives.
The surface rt is equipped with a front-end P recording camera with a good picture quality. It is already quite good as a video call camera.
The rear camera of surface RT also supports
