I'd like to add an additional IMU/GPs to my A3.  Two hopefully easy questions.

• Can I add just one or do I have to add two.  (Pretty sure I can add just one)
• In the manual it shows @3 connecting to one side of the A3 module and #3 connecting to the other.  If I'm adding only one, does it matter which side I plug it in?  (I'd like to connect on the same side as the PMU
