typing Board. Figure B-3 shows the four places where cuts should be made. An exacto
knife would work nicely to cut the traces. Alternatively, a small standard screwdriver may
be carefully and forcefully used to wipe through the PCB traces.

Demonstration Hardware on Prototyping Board
The power LED (PWR) and the RESET switch remain connected. Jumpers across the
appropriate pins on header JP1 can be used to reconnect specific demonstration hardware
later if needed.
Note that the pinout at location JP1 on the bottom side of the Prototyping Board (shown in
Figure B-3) is a mirror image of the top side pinout.
The Prototyping Board provides the user with RabbitCore 2000 connection points brought
out conveniently to labeled points at headers J2 and J4 on the Prototyping Board. Small to
medium circuits can be prototyped using point- to-point wiring with 20 to 30 AWG wire
between the prototyping area and the holes at locations J2 and J4. The holes are spaced at
0.1" (2.5 mm), and 40-pin headers or sockets may be installed at J2 and J4. The pinouts for
locations J1 and J3, which correspond to J2 and J4, are shown in Figure B-4.
