Design of a Programmable USB I/O Main-Board with Development Features

The strategy this work follows as to achieve its goal, is to put a very first stone in the way of making a USB peripheral. This is done by developing a USB I/O main board that features some properties usually known of development board; however, this main-board is best identified as an I/O board as it remains in the final product (i.e. it is employed by the final USB peripheral), this identification, called the main-board's description. The main-board developed as a moderate number of sub-circuits that achieve several functions, the choice of connectors used to plug LEDs, switches and daughterboard.
