Arduino Yún Shield Adds Ethernet and WiFi to Arduino Boards for $50

You can now add WiFi to Arduino for about $3 thanks to ESP8266, and it’s been long possible to add Ethernet with ENC28J60 module now selling for the same $3. Alternatively, if you want some a little more powerful, you could also use IoT modules running OpenWrt such as a $30 WrtNode or $13 LinkIt Smart 7688 both capable of supporting Ethernet with some hacks. But if you’ve been used to Arduino Yun, have a few spare Arduino boards, or simply think the other solutions are just too cheap, Arduino LLC has just launched Arduino/Genuino Yún Shield for $49.90 / 43.90 Euros. Arduino Yún Shield specifications:

SoC – Qualcomm Atheros AR9331 MIPS WiSoC @ 400 MHz
System Memory – 64 MB DDR2
Storage – 16 MB flash
Connectivity – 10/100 M and 802.11 b/g/n WiFi
USB – 1x USB 2.0 host port
Board interfacing – SPI and HW Serial
Misc – 5 LEDs (WiFi, Power, Ethernet, Activity and User); Reset shield and config reset buttons
Operating Voltage – 3.3V

The shield is compatible with Arduino Uno, Zero, 101, Diecimila, Due, Duemilanove, Leonardo, and Mega2560 boards.

The Yún Shield run OpenWrt-Yun and uses the Bridge library just like Arduino Yún board. You can find all details including documentation, hardware design files, and Arduino IDE on Arduino Yún Shield wiki.
