Spark Core: Arduino-Compatible "Wi-Fi for Everything"

Spark Core Board

The "Spark Core" from Spark Devices is an open-source, Arduino-compatible board  designed to greatly simplify the task of adding wireless Internet connectivity to things, especially DIY projects. The Spark Core Kickstarter project just closed on June 1st, and was a huge success with over 5,500 backers pledging $568K, vastly exceeding its $10K funding threshold.

The essential Spark Core components are a 72MHz ARM Cortex M3 microprocessor, a Wi-Fi wireless module, and a USB interface. Microprocessor input and output pins provide interfaces for controlling and communicating with the target hardware. The user develops software for the Spark Core with the popular, easy-to-learn and easy-to-use "Wiring" software development platform. Programs can be uploaded through the Wi-Fi or USB interfaces.
