Notes:
denotes power or ground signals.
The KEY pins are to guarantee proper module installation. PinA1 will be removed and the female side
plugged for 5.0V I/O signals and PinD30 will be modified in the same manner for 3.3V I/O. It is
recommended that both KEY pins (A1 and D30) be electrically connected to GND for shielding.
KCC boards have them as NC (not connected).
