* The shaded area denotes power or ground signals.
* 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
recommended that both KEY pins (A1 and D30) be electrically
connnected for GND for shielding.
