−RPi.GPIO supports referring to GPIO pins using either the physical pin numbers on the GPIO connector or using the BCM channel names from the Broadcom SOC that the pins are connected to. For example, pin 24 is BCM channel GPIO8. To use physical board pin numbers, call:

−Either method will work. The BOARD number scheme has the advantage that the library is aware of the Raspberry Pi model it is running on and will work correctly even if the Broadcom SOC channel names change in the future.

In the zynth we use GPIO.setmode(GPIO.BCM)
