I have been reading this forum and many other forums for the past three months and have decided to jump on the pixel train. I am totally new to this so I want to apologize in advance for any dumb question I might ask now or in the future. Initially my plan was to start small this year and just do little outline of the house and possibly the garage doors, I figured the F4V2 could handle that with no problem and then add a little more next year. I will be using 12V WS2811 bullet pixels. The wife and the kids noticed all the reading i was doing, the youtube videos of different displays i was watching and now they want more. They want leaping arches, matrix and mega trees. I explained the cost and we agreed on a small house outline and garage doors , maybe two or four leaping arches and a smaller probably 8 foot 180 degree tree. I came back here and noticed the Expansion Board and the Receiver Boards. I figure i can use the F4V2 for the house and the garage doors and possibly windows or something else. My question is, how many of the Receiver boards do you recommend for the 8 foot tree? Can I just use 1 ? How many boards will I need for the leaping arches? Watching youtube each arch will use 150 leds (a 5M strip cut in half). Any help will greatly be appreciated and once again i apologize for these dumb questions.
