7i92 P5

Is P5 on the 7i92 (ie the pair of round + square pads on the PCB) functionally identical to P3, so that I can apply 5V to P5 rather than P3? It's identified on the board but no mention in the manual.
I'm just tidying things up and don't want to make a ££ schoolboy error.

Thanks!
 

Yes, they are in  parallel.

 

Thanks, PCW.
