Table B-1 lists the electrical, mechanical, and environmental specifications for the
RCM3700 Prototyping Board.
B.1.3 Power Supply
The RCM3700, RCM3710, RCM3720, and RCM3750 operate from a regulated 4.75 V to
5.25 V DC power source. Only +5 V DC is supplied to the TCM_SMT_SOCKET socket.
The RCM3700 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 RCM3700 Prototyping Board.
The RCM3700 Prototyping Board itself is protected against reverse polarity by a Shottky
diode at D2 as shown in Figure B-3.
