Embedded systems today are most versatile at development and are most popular in many day-to-day applications. The reduction of an entire CPU-based motherboard to a small portable system is possible due to the use of high speed arm based microcontroller (LPC2478). This application dedicated board is used for presentation purposes which is compact, small enough to fit in a pocket. This system has its own set of software drivers and utilities for connection to USB devices and Human Interface Device (HID) which makes it highly compatible to any set of mass USB mass storage devices. The HID can be a keyboard or a mouse but in this board it is simple push buttons.
