The P10 panel can still turn on without 5V Power Input if it only uses one panel, but to increase brightness it must be added with 5V Power Input. 
5V Power Input must also be used if using more than one P10 Panel.

I only tried this code on a single P10 panel and used SystemFont5x7

      ↓        If you use two or more P10 panels that are connected to the bottom, displaying scrolling text from the side will be fine, 
 ____________  but for scrolling text display from top to bottom it might be problematic.
