Datasheet

With just a little effort you can make this shield plug-n-play with the Mega/Leonardo. Look at the bottom of the shield

and find the area with the 6 jumpers. Three of them are closed, and three are open. Solder close the three ICSP

jumpers.

You can then cut the small line in between the #11, #12, #13 pads. This will free up digital #11, 12, and 13 for you to use

on the Leo or Mega.

That's it! No software or firmware hacking other than that is required.
