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).
