Expansion Port A9 Notes
If you look closely at the ProtoSnap board, you’ll notice that sew tab A9 is shared between the switch and an
expansion port. Because of this, remember: if you’re using the A9 expansion port, ensure that the switch is
turned OFF to keep the input or output signal from shorting to ground.
