I’m having trouble comparing the two Sparkfun uBlox Zed-F9 GPSS boards… one named RTK; one named RTK2. Is there any difference? I see from the photos that the two uBlox chips have different last numbers on their module model number. I see the antenna connections are different… SMA vs uFl. They also have different backup batteries. But is there any other difference that would affect performance and, therefore, my choice?
Thanks
