The Prototyping Board comes with the basic components necessary to demonstrate the
operation of the RCM3305/RCM3315. Four user LEDs (DS3–DS6) are connected to
alternate I/O bus pins PA0–PA3 pins of the RCM3305/RCM3315 module via U8, and may
be driven as output indicators when controlled by PE7 and PG5 as shown in the sample
applications. Two switches (S2 and S3) are connected to PG0 and PG1 to demonstrate the
interface to the Rabbit 3000 microprocessor. Reset switch S1 is the hardware reset for the
RCM3305/RCM3315.
The Prototyping Board provides the user with RCM3305/RCM3315 connection points
brought out conveniently to labeled points at J8 and J9 on the Prototyping Board. Although
locations J8 and J9 are unstuffed, 2 × 17 headers are included in the bag of parts.
RS-232 and RS-485 signals are available on screw-terminal header J14, quadrature decoder
inputs are available on screw-terminal header J5, and digital inputs are available on screw-
terminal header J6. A 1 × 5 header strip from the bag of parts may be installed at J12 for four
sinking digital outputs. The clocked Serial Port B signals from the RCM3305/RCM3315
are used for the serial flash, and cannot be accessed via header J13 on the Prototyping
Board.
If you don’t plan to use the LCD/keypad module, additional signals may be brought out on 1 × 5
and 1 × 8 headers from the bag of parts that you install at J15 and J16. If you don’t plan to use
the stepper-motor control option, additional CMOS outputs are available via a 1 × 8 header
that you install at J10.
There is a 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
one edges of the prototyping area. Small to medium circuits can be prototyped using point-
to-point wiring with 20 to 30 AWG wire between the prototyping 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.
B.4.1 Adding Other Components
There are two sets of pads for 6-pin, 16-pin, and 28-pin devices that can be used for sur-
face-mount prototyping devices. There are also pads that can be used for SMT resistors
and capacitors in an 0805 SMT package. Each component has every one of its pin pads
connected to a hole in which a 30 AWG wire can be soldered (standard wire wrap wire can
be soldered in for point-to-point wiring on the Prototyping Board). Because the traces are
very thin, carefully determine which set of holes is connected to which surface-mount pad.
