RabbitCore RCM4000
Table B-1 lists the electrical, mechanical, and environmental specifications for the Proto-
typing Board.
B.3 Power Supply
The RCM4000 requires a regulated 3.0 V – 3.6 V DC power source to operate. Depending
on the amount of current required by the application, different regulators can be used to
supply this voltage.
The Prototyping Board has an onboard +5 V switching power regulator from which a
+3.3 V linear regulator draws its supply. Thus both +5 V and +3.3 V are available on the
Prototyping Board.
The Prototyping Board itself is protected against reverse polarity by a Shottky diode at D2
as shown in Figure B-3.
