I'm having trouble finding the correct board. I was told the rev f4 is not the same as cc3d? Could someone link me a legit branded board?
Thanks!!

All design files for Atom, CC, CC3D, Revo are open-sourced

So everyone can produce them. You have to ask seller if something he/she sells follows original design or is it modified version.
When it comes to Revolution or Copter Control 3D (CC3D). Revolution is targeted for auto-piloting and has better micro-controller than CC3D. On another hand CC3D is still a great flight-controler but useful for racers. I am using CC3D on my big 450mm quad and I am very happy with it.

If you want high quality expensive board that is not produced by Chinese then you have options
http://www.farwestrotors.com/#farwestrotors which is the same as Revo Nano
or
http://www.hobbiesfly.com/taulabs-sparky2-0.html which is like Revo with newer MPU9250 but flies as good as Revo

Revolution (incorrectly called by Chinese cloners Revo CC3D) is no longer produced by original designer, but derivatives, clones or even boards following original design can be found and bought from different sources.

I just want the right board for all of the gps stuff and one the is compatible with librepilot. All the ones I find on eBay say open pilot f4 naze32 blah..

For 15.09 version you want a board that says "openpilot revolution or revo" (only clone boards are made)
"openpilot nano" is no longer made

For upcoming release, you can get a Sparky2 or Sparky 2.0 (not one with an L shaped board, that is old version)
