So.  First, I think I had the 7x7 package?  Or did I have the 4x4
package to start with?  I don't know.  Anyway.  I've always had the 4x4
pinout, and the chips that I've ordered are the 4x4 ones so.  That's
what we're doing.

Using some random SMD footprint for it as the moment, because I don't
know what package we're actually using.
