    Hello –

    I’m going to be using the 1sheeld+ with an Uno R3, and I was wondering what I/O signals are used by the 1sheeld+. I imagine it varies depending on the type of sheeld I’m using. Is there a reference I can use to determine which signals are required for each particular application? I was hoping to have a couple of analog ins available on the Uno, but it appears that A0 thru A5 are connected… but are they all used in every case? Thanks.
