2.1 POWER SUPPLY

Power can be supplied to the Multimedia Expansion Board through the DC connector

located on the Multimedia Expansion Board (Figure 2-1). By connecting a 9-14V power

supply to the DC connector, the Multimedia Expansion Board and starter kit will receive

the proper voltages. The user can also supply power via the starter kit. However, if the

application uses multiple features of the Multimedia Expansion Board, it is

recommended to use 9-14V power supply.

Multimedia Expansion Board.

CAUTION

When connecting the Multimedia Expansion Board or starter kit, do not have power

applied when connecting the DC power supply. Failure to heed this caution could result

in hardware damage.
