RabbitCore RCM2100
B.1.2 Prototyping Board Expansion
The Prototyping Board comes with several unpopulated areas, which may be filled with
components to suit the user’s development needs. After you have experimented with the
sample programs in Chapter 4, you may wish to expand the board’s capabilities for further
experimentation and development. Refer to the Prototyping Board schematic (090–0116)
for details as necessary.
Module Extension Headers The complete pin set of the RCM2100 module is duplicated at these
two headers. Developers can solder wires directly into the appropriate holes, or, for more flexible devel-
opment, two 40-pin header strips can be soldered into place. See Figure B-5 for the header pinouts.
RS-232 Port Two 2-wire or one 5-wire RS-232 serial port can be added to the Prototyping Board by
installing a driver IC and four capacitors where indicated. The Maxim MAX232 driver chip or a similar
device is recommended for U2. Refer to the Prototyping Board schematic for additional details.
A 10-pin 0.1" spacing header strip can be installed at J6 to permit connection of a ribbon cable leading to
a standard DE-9 serial connector.
NOTE: The RS-232 chip, capacitors and header strip are available from electronics dis-
tributors such as Digi-Key and Mouser Electronics.
Additional LEDs Two additional LEDs (supplied with the development kit) can be soldered into place
at DS4 and DS5. The cathode lead (longer of the two, marked by a flat on the LED case) should go
towards the module.
Prototyping Board Component Header Several I/O pins from the module are hardwired to the
Prototyping Board LEDs and switches.
To disconnect these devices and permit the pins to be used for other purposes, cut the traces between the
pin rows. Use an exacto knife or similar tool to cut or break the traces crossing JP1, in the area indicated
To permit selective reconnection of the devices, jumpers may be placed across the 8-pin header strip at
JP1.
