Hello,
Unfortunately that shield never made it into production. I will have a look round and see if I can find a spare, unused board...and get back to you.
If you're comfortable at spinning your own PCB's I've attached the design files. We named it CoreInput, there is not much to it really. If you like soldering you could make up something relatively quickly using the prototyping area of the 2x2 shield.
Paul will advise on how to to install the correct drivers.
Kind Regards
Iain
