B.4 Using the Prototyping Board
The Prototyping Board is actually both a demonstration board and a prototyping board.
As a demonstration board, it can be used to demonstrate the functionality of the RCM3100
right out of the box without any modifications to either board. There are no jumpers or dip
switches to configure or misconfigure on the Prototyping Board so that the initial setup is
very straightforward.
The Prototyping Board comes with the basic components necessary to demonstrate the
operation of the RCM3100. Two LEDs (DS1 and DS2) are connected to PG6 and PG7,
and two switches (S2 and S3) are connected to PG1 and PG0 to demonstrate the interface
to the Rabbit 3000 microprocessor. Reset switch S1 is the hardware reset for the
RCM3100.
The Prototyping Board provides the user with RCM3100 connection points brought out con-
veniently 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 J2 and
J4, which correspond to headers J1 and J2, are shown in Figure B-4.

The small holes are also provided for surface-mounted components that may be installed
around the prototyping area.
There is a 2.0" × 3.5" through-hole prototyping space available on the Prototyping Board.
+3.3 V, +5 V, and GND traces run along the edge of the Prototyping Board for easy access.
