A recent press release from Atmel has announced the introduction of the Arduino WiFi Shield 101 which can be connected to any modern Arduino R3 board to give connectivity to the Internet via any traditional Wi-Fi access points. This new Shield is said to offer secure, cost-effective, high-performance Wi-Fi connectivity. The new board is targeted at Arduino IoT applications and incorporates Atmel’s WINC 1500 wireless network controller offering IEEE 802.11 b/g/n (1×1) at up to 72 Mbps and supporting IEEE 802.11 WEP, WPA2 security enterprise.

Ray Wang wrote a blog post review of the Hi-Link HLK-RM04 Serial-to-WiFi module:
It’s a pretty easy-to-use and low-cost solution to add WiFi capability to Arduino or similar microcontroller boards. Basically it allows you to receive/send Ethernet buffers through serial RX/TX pins. Programming wise, it’s similar to using the standard Arduino Ethernet shield. The module can also function as a WiFi router for changing configurations etc.

WiFi module in a version with a pin-header significantly simplifies development of applications.
Basic version of the WiFi module WizFi250 from company WizNet is probably familiar to you from our article WizFi250 – WiFi quickly, easily and cost-effectively. The newest modification of this module is a version with a „H“ suffix marking a version with a pin-header.
As you already may suspect, it is a version intended for development, as the module doesn´t have to be soldered to a baseboard (by means of hot-air reflow). WizFi250-H can be beneficial not only for development, but also for usage in a target device, where it isn´t necessary to maintain the lowest possible construction height (baseboard + WiFi module). At the same time, this combination enables to assemble another components on a baseboard – below the WiFi module.
From the construction point of view, the WizFi250-H module is solved as a combination of the WizFi250 module with a small PCB with 2x double pin header (1.25mm). As for other features, the module is identical to the original module, that´s why they have the same datasheet WizFi250. WizFi250H can be used with the WizFi250-EVB development board. We bring you a comparison of both versions – with and without a pin header on attached pictures.

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.
