Introduction

This Mega IO Expansion Shield can solve the disadvantage of instability when using the bread board to build the circuit to connected to sensors. It includes 3 Xbee slots, 1 microSD slot, Arduino shield headers to plug in most Arduino shields. It also includes a prototyping area and breakouts for Digital pins 14 to 53, and Analog pins 6 to 15.
