Hello,
I've recently build according to the featured tutorial on Make: (
http://makezine.com/projects/make-37/gps-cat-tracker-2/) the TinyCircuits GPS Tracker and uploaded the Sketch but it won't work. Once i've unplugged the USB-Shield and inserted the lithium-battery, nothing happens. I've bought the TinyDuino with lithium support and the featured lithium battery.
Also Google Earth shows me "No Data Found" once i've tried to import the GPS.nmea.
Does anyone knows some help? This is frustrating.
