Getting Started
Caution: If the 140-pin connector is damaged due to an improper assembly, the reader must contact their
Intel Sales representative for module replacement.
2.2.1 Connecting Power from an AC Adapter
Use the following procedure to provide power to the SA-1110 Development Board from an AC
adapter:
Caution: The following procedure assumes that the jumper (shunt) for J22, the Master Power Clip for the
Li-ion battery, has been disconnected and that all power associated with the SA-1110 Development
Board is off. For more information about Li-ion battery considerations, see Chapter 6.
Note: A very high value capacitor of 0.33 Farads (super cap) is connected in parallel with the power input
from J10. This capacitor provides enough power to support the system for several minutes in sleep
mode when power from J10 is removed.
1. Verify that the jumper (shunt) for J22 is not on the Master Power Clip (J22 should appear as
two bare pins).
2. Select the appropriate AC adapter to DC converter device (wall brick) depending upon
whether you are in a 110-volt or 220-volt environment.
