GND/3.3V KEY2
Notes:
1. The shaded area denotes power or ground signals.
2. The KEY pins are to guarantee proper module installation. Pin-A1 will be removed and the female side
plugged for 5.0V I/O signals and Pin-D30 will be modified in the same manner for 3.3V I/O. It is highly
recommended that both KEY pins (A1 and D30) be electrically connected to GND for shielding.
DLAG boards have them as NC (not connected).
