The Plan....The whole point was to design a series of small boards that could be used as building blocks as well as individual modules. They can be mounted on a panel or put on a motherboard and used a single board modular. Most of the boards are designed with the i/o connectors all on one side of the board. Using 90 degree headers they can even be mounted vertically.

More information about the modules, diagrams, and mods can be found here"
