The Uno uses D13 for its LED, but could be shared in a pinch.
As far as I can tell, that uses Arduino signals D4,D5,D6,D7,D8,D9 and AD0. The Analog Shield uses Uno D2,D3, D5, D6 (P7-3,4,6,7) for its data to or from the Uno.Īs an aside, on my specific project, I have a Sainsmart 2x16 LCD Keypad-Shield that will go atop my custom shield.
I made a copy of my in-progress layout, and stripped out the components. I think it is correct, but I have not had a board built. My board may end up bigger than the Analog shield, but I have put a board outline into the file that matches the 2.1 by 3.1 inch dimensions of the Analog Shield. The component designations and pin numbers match those of the Analog Shield. It could even be useful to somebody making an unrelated shield for Uno by stripping out the P1, P2, and P3 headers on the left and adjusting the board outline. I thought I might post what could be a useful DipTrace base layout for a shield to use with the Analog Shield on an Arduino Uno.
