Figure 39 shows power inputs of the OSD3358-SM-RED platform. A combination of the AC,
USB and battery inputs can be used to power the board. To protect the board from power surge,
reverse polarity and transient input voltage behavior, the AC adapter input signal goes through
an input protection circuit shown in Figure 39. To power the board using a 1S Li-Po battery, the
following hook up is required.
