Notes
Can be used to power auxiliary equipment.
Note: This pin can only be used as power out.
Digital input – Connect to pin 1 to activate,
or leave floating (unconnected) to deactivate.
Digital output – Connected to pin 1 when
activated, floating (unconnected) when
deactivated. If used with an inductive load,
e.g. a relay, a diode must be connected in
parallel with the load, for protection against
voltage transients.
