RabbitCore RCM3700 User’s Manual
Power Connection
Note that the 3-pin header is symmetrical, with both outer pins connected to ground and
the center pin connected to the raw DCIN input. The cable of the AC adapter provided
with the North American version of the Ethernet Connection Kit ends in a plug that
connects to the power-supply header, and can be connected to the 3-pin header in either
orientation.
Users providing their own power supply should ensure that it delivers 7.5–15 V DC at
200 mA. The voltage regulator will get warm while in use.
Linear Power Supply
jack is routed to a 5 V linear voltage regulator. The regulator provides stable power to
the RCM3720 module and the Prototyping Board.

nected to the PF4 and PB7 pins of the RCM3720 module and may be read as inputs by
sample applications.
Two LEDs are connected to the PF6 and PF7 pins of the RCM3720 module, and may
be driven as output indicators by sample applications.
Prototyping Area
of through-hole components. +5 V and ground buses run along the bottom 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 or wire-wrap wire.
Module Extension Headers
cated at header J2. Developers can solder wires directly into the appropriate holes, or,
for more flexible development, a 2 × 20 header strip with a 0.1" pitch can be soldered
into place. See Figure B-14 for the header pinouts.
RS-232
RCM3720 Prototyping Board. A 2 × 5 header strip with a 0.1" pitch is installed at J7 to
allow you to connect a ribbon cable that leads to a standard DB9 serial connector.
Two 3-wire serial ports or one 5-wire RS-232 serial port are available at header J7.
