Wireless communication between multiple Arduinos

Awesome! Thanks!

I'm assuming this is the module here: https://www.gearbest.com/transmitters-receivers-module/pp_218375.html?currency=CAD&vip=1830451

I went and looked at this tutorial as well for the units Arduino Wireless Communication – NRF24L01 Tutorial - YouTube
It says the communication maxes out at 6 units though?
