The Yun board for Arduino aims to take DIYers into the cloud. The Yun is the first of a family of low cost, low power Arduino boards that run Linux and support Wi-Fi, following the trend toward the Internet of Things (IoT). Yun, named for the Chinese word for cloud, is designed to let the average tinkerer link a new Linux gadget to the Web using a simplified browser interface.
Yun links to the Web via the Hornet AR9331 Wi-Fi chip from Qualcomm Atheros, which supports 2.4 GHz networking and runs a custom distribution of Linux. The Yun roadmap features five products and two separate product families, including some boards designed to run up to four years on two AA batteries.
The board is supported by client software from Temboo, and a library of over 100 APIs that facilitate connection to popular Web services such as Facebook, Twitter and OAuth.
