the cable to the z axis was removed, but it's included, I was going to hookup something else to a2 input. it could be hooked back up if want to use z sensor.
new connector for the IR cable on the underside of the shield. I don't need this connector, so it's for you with the shield. and the headers to go down to ardupilot board, they're nice already the right lengths.
I have a solder sucker coming in the mail, I'll clear up some of the holes that have solder in them, so easy to put new connections in.
