Just ordered two dAISys! Can't wait to start working with them on my autonomous boat. My goal is to have a teensy 3.1 grab the Nmea data from the dAISy. Then at preset times have the teensy send the latest nmea string via satellite to an email address where I can decode it and be aware of local ships in the area. Sort of a hybrid on-board/ off-board collision avoidance system. A question, is the TTL serial output already part of the dAISy or is that an extra purchase. If it is on the dAISy, how do I access it? Ahh never mind I see the TTL output in the Eagle file. What type (manufacturer, type) of antenna found works best with dAISy? Thanks for the great work!
