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 Development Kit ends in a plug that connects
to the power-supply header, and can be connected to the 3-pin header in either orienta-
tion. A similar header plug leading to bare leads is provided for overseas customers.
Users providing their own power supply should ensure that it delivers 7.5–30 V DC at
500 mA. 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 RCM3750 module and the Prototyping
Board.

I/O Switches and LEDs
nected to the PF4 and PB7 pins of the RCM3750 module and may be read as inputs by
sample applications.
Two LEDs are connected to the PF6 and PF7 pins of the RCM3750 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 at both edges 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.
LCD/Keypad Module
in directly to headers LCD1JA, LCD1JB, and LCD1JC. The signals on headers
LCD1JB and LCD1JC will be available only if the LCD/keypad module is plugged in
to header LCD1JA. Appendix C provides complete information for mounting and using
the LCD/keypad module.
Module Extension Headers
module is duplicated at header J3. Developers can solder wires directly into the appro-
priate holes, or, for more flexible development, a 2 × 20 header strip with a 0.1" pitch
can be soldered into place. See Figure B-4 for the header pinouts.
Analog I/O Shrouded Headers
Prototyping Board is available on shrouded headers J8 and J9. See Figure B-4 for the
header pinouts.
