You may find a project for making the Arduino Pro Mini itself in the KiCAD “Templates” folder. That is enough information for you to construct a footprint and symbol relevant to your particular project. Look in \share\kicad\template\Arduino_Pro_Mini.
Be careful with modules in the Arduino world - they are NOT all mechanically interchangeable! I have had problems with this when using both the Arduino Pro Mini, and the Real Time Clock module (called “ZS-042” by some vendors). See comments at Arduino Blank Shield Available? - #10 by TomC .
