From the project

A Smoothie-compatible board with a modular design.

Overview ======== This is a plan to make a RepRap electronics solution capable of running the Smoothie firmware. The board will be built around the LPCXpresso 1769, with a more modular design in the spirit of RAMPS. More information about the RepRap project can be found at http://reprap.org, and more information about Smoothie can be found at http://smoothieware.org.
