B.1.1 Prototyping Board Features
Power Connection
—+5 V, +3.45 V, and AC1_DCIN voltages are supplied to the Pro-
totyping Board by the PowerCore module. These voltages can be used to power cus-
tomer-installed parts in the prototyping area.
Power LEDs
—The two power LEDs at DS3 and DS4 light whenever +3.45 V and + 5 V
is being supplied to the Prototyping Board from the PowerCore module.
Prototyping Area
—A generous prototyping area has been provided for the installation
of through-hole components. +5 V, +3.45 V, and Ground buses run along one edge of
this area. Several areas for surface-mount devices are also available. Each SMT pad is
connected to a hole designed to accept a 30 AWG solid wire.
Reset Switch
—A momentary-contact, normally open switch is connected directly to the
PowerCore module’s /RESET_IN pin. Pressing the switch forces a hardware reset of the
system.
I/O Switches and LEDs
—Two momentary-contact, normally open switches are con-
nected to the PC3 and PG4 pins of the PowerCore module and may be read as inputs by
sample applications.
Two user LEDs (DS5–DS6) are connected to I/O pins PD5 and PC2 of the PowerCore
module.
LCD/Keypad Module
—Rabbit Semiconductor’s LCD/keypad module may be plugged
in directly to headers LCD1:JA, LCD1:JB, and LCD1:JC. The signals on headers
LCD1:JB and LCD1:JC will be available only if the LCD/keypad module is plugged in
to header LCD1:JA.
Appendix C provides complete information for mounting and
using the LCD/keypad module.
Module Extension Header
—The PowerCore module’s pin set is duplicated at header
J4. Developers can solder wires directly into the appropriate holes, or, for more flexible
development, a 2 × 25 header strip with a 0.1" pitch can be soldered into place. See
Digital I/O
—Four digital outputs and a +K connection are available on header J2. Two
digital inputs are available at header location J4. See
Figure B-3 for the header pinouts.
Triacs
—Two Z0107MN triacs are installed on the Prototyping Board, and can be used
for general-purpose AC switching applications such as electrovalves, pumps, door
locks, small lamp control, and fan-speed control. Their outputs are available on header
J2. Miniature incandescent lamps may also be installed on the Prototyping Board to
observe the triac operation.
RS-232
—Two 3-wire serial ports or one 5-wire RS-232 serial port are available on the
Prototyping Board at header J1.
RabbitNet Port
—One RS-422 RabbitNet port is available to allow RabbitNet periph-
eral cards to be used with the PowerCore Prototyping Board.
