MEGA Sensor Shield
This shield board plugs on top of an Arduino MEGA (1280 or 2560) and makes it easy to connect to all the MANY Digital Inputs and Outputs and the Analog Inputs. This is particularly good for Home Automation or other high I/O projects with many LEDs or controls where connections to the Mega can be a major problem.
NOTE: This is the latest version of a Mega Sensor shield. Other sellers have earlier versions labelled V2 or V3 !
