Funnel I/O (FIO) is an Arduino compatible board designed by Shigeru Kobayashi, based on the original design from LilyPad

Funnel is a toolkit to sketch your idea physically, and consists of software libraries and hardware. By using Funnel, the user can interface to sensors and/or actuators with various programming languages such as ActionScript 3, Processing, and Ruby.

FIO is compatible with Funnel. It has connections for a Lithium Polymer battery and includes a charge circuit over USB. An XBee socket is available on the bottom of the board. The FIO has been designed to be wirelessly reprogrammable. Checkout Lady Ada’s reference page on XBee wireless reprogramming.
