Mapped source · Banana Pi BPI-M2 Zero documentationOfficial- Official Banana Pi docs state the 40-pin header matches the Raspberry Pi 3 physical connector.
- Signal names are Banana Pi / Allwinner functions, not Raspberry Pi BCM GPIO numbers.
- GPIO uses 3.3 V logic; 5 V header pins are power rails and must not be driven into GPIO.
