RabbitCore RCM3900 User’s Manual
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 (J2)—the center pin of J2 is always connected to the positive terminal,
and either edge pin is negative.
Users providing their own power supply should ensure that it delivers 8–30 V DC at 1 A.
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 RCM3900 module and the Prototyping
Board. The voltage regulators will get warm while in use.

nected to the PG0 and PG1 pins of the RCM3900 module and may be read as inputs by
sample applications.
Four user LEDs (DS3–DS6) are connected to alternate I/O bus pins PA0–PA3 pins of
the RCM3900 module via U8, and may be driven as output indicators. PE7 and PG5
control the registers in U8 as shown in the sample applications.
Prototyping Area
of through-hole components. +3.3 V, +5 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.
LCD/Keypad Module
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.
