I am in the beginning of year one with my first F16v2. It was easier than expected to set up and to run. I loved it. It is powering a 12 string pixel tree with 12 V pixels and a couple of straight runs along the driveway. Next year I'm looking to add some mini pixel trees and possibly some arches on the opposite side of the driveway, approximately 50 feet from the falcon. So I'm wondering as the title implies if I should buy an expansion board and keep it 50 feet away from the beginning of the rest of my yard. Or if I should purchase a new F 16. I'm totally unfamiliar with power injection, but I would learn it. I'm unfamiliar with how an expansion board works, I will learn it. If I do buy an expansion board, do I need to do anything to get my computer to see it or does it automatically see it?
