RabbitCore RCM4100
Selected signals from the Rabbit 4000 microprocessor are available on header J2 of the
Prototyping Board. The remaining ports on the Rabbit 4000 microprocessor are used for
RS-232 serial communication. Table B-2 lists the signals on header J2 and explains how
they are used on the Prototyping Board.
There is a 1.3" × 2" through-hole prototyping space available on the Prototyping Board.
The holes in the prototyping area are spaced at 0.1" (2.5 mm). +3.3 V, +5 V, and GND traces
run along the top edge of the prototyping area for easy access. Small to medium circuits
can be prototyped using point-to-point wiring with 20 to 30 AWG wire between the proto-
typing area, the +3.3 V, +5 V, and GND traces, and the surrounding area where surface-
mount components may be installed. Small holes are provided around the surface-mounted
components that may be installed around the prototyping area.
