I'll guess the SD card slot is for logging a lot of data. True? Is that its only use? How much internal memory is setup for logging? How much logging will that give me? (tough question)
I'm trying to figure out if I need to get a card.
Does the V2 support any kind/size of card?
With the card installed do I get to use both the internal and external (sum total), or are they seperate storage spaces?
