Very Basic Questions

[NOLA26]

I ordered a Falcon F16v3 controller.  I already have an outdoor enclosure, power supply, and a Raspberry Pi.  I plan on starting small this year with maybe 10 arches of 50 pixels each, roof outline which is about 75' of lights needed.  I figure 3 or 4 strings of 100 will probably cover it.  So, what I want to know is how many strings pixel nodes can the Falcon handle per output?  The furthest distance away from the controller any string will be is probably about 30'-40'.  Will I need to inject power at any point?  And my last question is about the Raspberry Pi.  Do I install special software to run the xLights show?  Is that the Falcon Pi player software?  Just trying to get some definitive information.  I have been reading this forum, and watching the videos but no one ever mentions this super basic stuff.  Thanks yall!

All of those questions and more have been asked and answered over and over.  'Search' is your friend.

from the Spec Sheet: F16V3 - 1024 pixels per output

It will depend if you use 5V or 12V pixels as to where and how much power injection you'll need. As a rough guide you can run this many pixels before requiring power injection: 
5V about 50 pixels
12V about 100 pixels
If the controller is a long distance from the pixels, you may need to inject power closer to the pixels due to voltage drop in long lengths of cable.

Length of cable will also affect data, this can be overcome by using higher quality cabling and/or null pixels.

Yes, the falcon pi player software is what you install on the Pi to run the show.
