Pinkie is a network based electronics prototyping board developed as a precursor to building large networked systems around physical devices. It has been designed to easily compose sensors and actuators that reside in different locations. Pinkie boards work in-relation with a suite of collaboration-oriented software services and interfaces to program and run distributed physical media, and to exchange data and functionality of devices over the Internet. Pinkies are inherently invisible, they hide behind the structures and only serve as facilitators to interface the physical world to the digital network.

Pinkie was part of Open I/O, a suite of software services and applications for composing and running distributed electronic media in a way that enables people to exchange data over the Internet.
