The model of this shield named Yun Shield, the feature of this shield is as its name. User can add this shield into Arduino (Leonardo, UNO, MEGA2560 etc) and “turn” the Arduino into device which has similiar features as Arduino Yun: support remote upgrade and use the Bridge library.
With this shield, user can easy to set up communcation between Arduino and Internet (via ethernet , wifi or 3g etc) and add support for USB flash, video. The detail user guide/ manual can be found in the dragino website and most Arduino Yun Sketch / examples can reuse with this Shield. This shield is under production and will be ready within one months time.

MediaTek has announced the MT6795 which the company has targeted at the high-end android 4G smartphones and tablet segment. According to the press release the 8-core processor also supports 2560 x 1600 resolution displays, FDD/TDD LTE technology, 802.11ac WiFi, Bluetooth, GPS, FM Radio, 2G and 3G wireless networks. The chip also supports video recording and playback at Ultra HD (4K2K) resolution using the H.265, H.264 and VP9 formats, supporting high-speed 1080p video recording at up to 480 frames per second allowing slow-motion playback on screens with 120 Hz refresh. An integrated 16MP camera image signal processor handles video input and MediaTek’s ClearMotion™ technology eliminates motion jitter to ensure smooth video playback at 60fps.

This is Part 2 of a series of blogs regarding the development of a wall-mounted server based on the Raspberry Pi, featuring WiFi and a colour touchscreen. Part 1 can be found here.
The enclosure I’m using, a re-purposed room thermostat casing, places some very tight constraints on the dimensions of the Raspberry Pi and PiTFT board.The plastic used in the case is quite sturdy, and is at least 2mm in thickness. Therefore the real inner depth of the case is about 12mm. As for the width of the Pi, we need to shave at least 4mm from the side. The Pi itself is 86mm wide, same with the PiTFT board, so we will need to find a way of making it closer to 82mm.

When you start hooking peripherals such as keyboard, WiFi dongle and mouse to a Raspberry Pi it’s not long before you run out of ports and need a USB hub, preferably powered so that it can supply the RPi as well. At this point cabling starts to take over your workspace.
The Raspiado board, launched on Kickstarter should help cut down on the tangle; it has the same dimensions as the RPi board and mounts on its underside via two (stackable) standoff pillars to leave the top GPIO and camera connectors open to whatever you’re building so that it won’t impede the RPi’s connectivity options.

The WifiDuino is the chip-sized Arduino + Wi-Fi + 128×64 OLED at low price that is easy to use.
WifiDuino is an open-source Arduino-compatible, wifi-enabled board. It allows users to use Arduino IDE (Integrated Development Environment) interface to write programs directly, and with Wi-Fi function. WifiDuino is user friendly, get started in no time. What’s different from Arduino Wi-Fi shield is that WifiDuino is a lot smaller in size, cheaper and easier to use.
WifiDuino is an open source project, which means you are welcome to develop and improve the project if you want. It is also ideal for beginners too. WifiDuino and Arduino are used the same chip. You can quickly learn how to make things with WifiDuino with its rich library resources from the Arduino database.

The xPico WiFi Shield supports simultaneous wireless LAN client connectivity and access point (AP) functionality. This makes it easy to securely connect to an Arduino microcomputer using web-based tools and interactive applications on smartphones or tablets. Its built-in controller ensures that there is no need for a wireless LAN driver on the Arduino microcontroller to configure wireless connectivity.
The xPico Wi-Fi Shield includes connection management software and a web-based configuration interface to manage connectivity complexity on behalf of the application developer. This significantly cuts down the development overheads for engineers, designers, students and hobbyists who need to quickly add smart Wi-Fi solutions to their Arduino designs.

Smartphone peripheral developers are limited to RF links via Bluetooth, NFC or WiFi when they need to pass data back and forth to the device. This can add significantly to costs and stand-alone peripherals also need batteries or an adapter for power. The Quick-Jack from NXP solves both problems; it turns the standard 3.5 mm stereo audio headphone socket found on most iOS or Android smart devices into a self powered data port and provides an interface for external switches, sensors or any other external equipment.
The Smartphone Quick-Jack Solution comprises a small board, a free example app for popular smartphone OSs, and design documentation.

Dynamic Near Field Communication tag, a new wireless technology that connects phones with MCU after wifi and Bluetooth, is your optimized NFC solution.
We are proud to bring about the Dynamic Near Field Communication tag (DNFC tag), an invention that who especially tech nerds and DIY lovers have been expected for long. It greatly outstands among traditional read-only NFC tags because it’s readable and rewritable and it can communicate with various platforms, to name several most popular: Arduino, Raspberry Pi, Leaf Maple stm32 and some more. It owns a high level of dexterity, thus making it efficient, easy to execute and user-friendly.
The clue is in the name: Near Field Communication. It allows NFC portable devices to establish peer-to-peer radio communications, delivering data from one to another by touching them or putting them very close together. Basically, when you get your phone (if it has NFC as a feature) close to something equipped with NFC – like a tag – it invokes an action on your device.

Connectors M.2 also called as NGFF have a chance to become a widely used standard in computers, communication equipment and M2M applications.
The newest member of the data connectors family in our offer are connectors Attend series 123, so called NGFF – New Generation Form Factor connectors, also known as „M.2“. Their main advantage is implementation of PCI Express 3.0, Serial ATA 3.0 and USB 3.0. buses into one connector. The connector is considerable miniaturized and at the length of only 21.8 mm it has up to 75 pins ( 0.5mm pitch/ 50V/0,5A). M.2/ NGFF are designed as a future standard for SSD memory media, WiFi, Bluetooth, GPS/GNSS, NFC and other modules. As it´s not a “specialty” of one producer but it´s a connector designed as an international standard, their usage in your device can be advantageous thanks to a supposed easy availability even in the future. An important fact is, that connectors are produced with various keying (A-M). That provides a possibility to differentiate various modules on one board and prevents improper connection (PCIe x2, PCIe x4,…).
M.2 connectors are designed for a direct insertion of PCB, i.e. one part of a connection (M) is a PCB and another part is the connector (F). Connectors support various PCB widths – 12, 16, 22 and 30 mm. Depending on a type, M.2 connectors also enable a double-sided assembly of components on a PCB.
Another novelties from the Attend production in our stock are interesting types for SIM cards, as well as combinations 2xSIM(115L-AB380), 2XSIM + uSD (115M-AB360) and other, which can be found below this article.
