I have this schematic here I'm trying to recreate in Kicad. I'm lost on the meaning of part "PH_A, P8".
As you might know in KiCAD the schematic symbols and the footprints are not coupled.
In order to recreate it use "conn_01x01" symbol in the schmatic editor(Eeschema). You can change its value to "PH_A". This symbol represents a single pin component, but it can be anything you want. You should refer to the pcb file of the attached project and search for "PH_A".
