Hows this look for a start?
I'd buy one.
I came across this thread while trying to source the same thing. I've been told about a Mega screw shield herehttp://www.aqualed-light.com/?sec=home&id=1758You will have to run it through a translator if you don't understand Portuguese. I was trying to find an online shop so I didn't have to email for an invoice, but this is all I've found so far.
Main characteristics of Screw Shield for the Arduino Mega:-Works on any Arduino Mega 2560/ADK/1280/Other/Clones.-Can be stacked with other shields over.-All pins of the Arduino Mega are replicated by terminals with screws being so simple to make any link without welds.-Have extra for signs of terminals GND, 5V, 3.3 V and VIN in order to easily feed on other external circuits.General appearance:
Does anyone have a clue as to a shield for the mega that would allow a 40 pin cable, short but long enough to access the other I/O on the mega... I have an LCD (Itead) and a shield for my mega but there is NO access to anything under that shield...I would hate to make one... 40 dollars or so??? the time isn't an issue just a one of or two of circuit board is more than I want to pay. Any Idea's?Doc
