High Frequency GPS updates

Hi Rob,

Got it, it makes sense. I will try the RX/TX simple serial comm with the Pi. So if the GPS will use AUXRX/AUXTX, setting up the RX/TX between the Notecarrier and the Pi 2 W, I would need to setup the card comm interface via which API? card.io, card.aux?

Thansk!
