Notes
Ground
Can be used to power auxiliary equipment.
Note: This pin can only be used as power out.
Digital input - Connect to GND to activate, or
leave floating (or unconnected) to deactivate.
Digital output - Uses an open-drain NFET
transistor with the source connected to GND.
If used with an external relay, a diode must
be connected in parallel with the load, for
protection against voltage transients.
