B.3.2 Prototyping Board
To maximize the availability of Jackrabbit resources, the demonstration hardware (LEDs,
switches, potentiometer, buzzer) on the Prototyping Board may be disconnected. This is
done by cutting the traces seen between and within the silk-screen outline of headers JP1
and JP2 on the Prototyping Board. Figure B-6 shows the 16 places where cuts should be
made. An exacto knife or high-speed precision grinder tool like a Dremel
work nicely to cut the traces. Alternatively, if safety is a major concern, a small standard
screwdriver may be carefully and forcefully used to wipe through the PCB traces.
Jumpers across the appropriate pins on headers JP1 and JP2 can be used to reconnect spe-
cific demonstration hardware later if needed. Each pin is labeled on the PCB to facilitate
placing the jumpers. The jumper positions are summarized in Table B-1.
