Thanks @JColvin! The drawing and STEP have exactly what I was looking for - this will make putting the rest of my mechanical design together much easier!

JColvin - Thanks for the quick response! Bitbanging the SPI on these pins in your library makes sense. That was not clear in the documentation so thanks for clarifying. Inner and outer rows is definitely more clear in the labeling of pins and is very helpful. Thanks again for your help, I'm looking forward to getting a few of these DMM Shields ordered - it looks like a great product! Matthew

Bianca, I do not yet have the DMM Shield in hand, but looking at the documentation shows that it is using Arduino I/O Pins 11,12,13 for SPI. The Arduino Mega/Due do not have SPI on those pins, they only have SPI accessible on the ICSP header and the Mega additionally has it broken out on the I/O header at the end of the board. The DMM Shield does not connect to either the ICSP or the I/O Header at the end of the Mega/Due. How are you suggesting that we connect SPI to the DMM Shield? My only thought is to Set the Mega pins 11,12,13 as Inputs and then to jump the SPI pins on the Mega/Due to
