Några av stiften i expansionsporten är avsedda för strömförsörjning av mindre, externa enheter. Anslut endast dessa stift om det krävs för den externa utrustningen. Man bör alltid försöka ta strömmen direkt från nätagget om det är möjligt. AUDIO GND är inte samma sak som GND, blanda inte ihop dem. Ett snedstreck framför signalnamnet (t.ex. /IPL0) anger att signalen är aktiv låg. nc - not connected, betyder att stiftet inte är anslutet.
