B.3.1 Demonstration Board
A relay, a thermistor, four additional LEDs, and a serial cable are included in a bag of parts
to further allow exploration of the Jackrabbit‘s operation.
The SPDT relay handles 120 V at 5 A with a 12 V activating coil. The layout to accept this
relay is included on the top side of the Prototyping Board. Note that the relay coil connec-
tions need to be wired to one of the sinking high-power outputs (HV0–HV2) of the Jackrabbit.
Install the relay on the bottom side of the Prototyping Board, as shown in Figure B-4.

NOTE: COIL(+) must be connected to a 12 V power supply when using the relay.
This is the nominal voltage supplied as +RAW when the transformer supplied with the
Development Kit is used, and in this case you may connect COIL(+) to +RAW. If you
use another power supply, connect COIL(+) to +12 V if +RAW is different.
NOTE: If you do use the transformer supplied with the Development Kit for COIL(+),
be aware that its voltage may be as high as 16 V at low current draws. This needs to be
taken into consideration if you plan to use a 12 V relay in critical applications.
