Arduino Expansion Shield IO Input Output DFRduino

INTRODUCTION
IO Expansion shield is one of the market favourites. Fast robotics prototyping made affordable and simple thanks to this design. Soldering and wiring often become a problem when a bridged connection happens and components break. Increasing time and cost for projects. Often, without this solution and a soldering station, wire cripping tools or soldering station, robot prototyping or electronics DIY becomes a very long term project.
