Main power input for either both module and carrier (default), or
for carrier only, when J64 is used.

The board can be supplied via the AC/DC adapter plugged into the power jack. Such adapters
have usually no connection to protective earth. Consequently, the potential of the
conductive parts on the board may drift. If a human touches such a part, this may lead to an
electric shock. The board must be grounded separately, if the unit is supplied via power jack.

To power the Qseven Module the power can be set to Ext/Int power by populating one of
the following resistors.
R468 – V_MOD_IN from internal (V_5V0_S5) [Default setting]
R467 – V_MOD_IN from external (V_3V0-5V25_IN)
