Prototyping Board Features - Rabbit RabbitCore RCM3209 User Manual

B.1.1 Prototyping Board Features
Power Connection
•
nection to the power supply. Note that the 3-pin header is symmetrical, with both outer
pins connected to ground and the center pin connected to the raw V+ input. The cable
of the AC adapter provided with Development Kit ends in a 3-pin plug that connects to
the 3-pin header (J9)—the center pin of J9 is always connected to the positive terminal,
and either edge pin is negative.
Users providing their own power supply should ensure that it delivers 8–24 V DC at
8 W. The voltage regulators will get warm while in use.
• Regulated Power Supply
routed to a 5 V switching voltage regulator, then to a separate 3.3 V linear regulator.
The regulators provide stable power to the RCM3209/RCM3229 module and the Proto-
typing Board.

• I/O Switches and LEDs
nected to the PG0 and PG1 pins of the master RCM3209/RCM3229 module and may
be read as inputs by sample applications.
Two LEDs are connected to the PG6 and PG7 pins of the master module, and may be
driven as output indicators by sample applications.
Prototyping Area
•
of through-hole components. +3.3 V, +5 V, and Ground buses run around the edge of
this area. Several areas for surface-mount devices are also available. (Note that there
are SMT device pads on both top and bottom of the Prototyping Board.) Each SMT pad
is connected to a hole designed to accept a 30 AWG solid wire.
Master Module Connectors
•
of the first RCM3000, RCM3100, or RCM3209/RCM3229 module that serves as the
primary or "master module."
Slave Module Connectors
•
lation of a second, slave RCM3209/RCM3229, RCM3100, or RCM3000 module. This
capability is reserved for future use, although the schematics in this manual contain all
of the details an experienced developer will need to implement a master-slave system.
Module Extension Headers
•
SLAVE RabbitCore modules are duplicated at these two sets of headers. Developers
can solder wires directly into the appropriate holes, or, for more flexible development,
26-pin header strips can be soldered into place. See Figure B-4 for the header pinouts.
