F.1.4 Onboard Power Supplies
The +3.3 V supplied to the RCM5600W powers most of the onboard circuits. In addition,
there is a +1.8 V DC linear regulator that provides the core voltage to the Rabbit 5000 micro-
processor. Other linear regulators supply the additional voltage levels needed by the Wi-Fi
circuits.
