Samsung 710 User Manual page 17

Through selection of the Jumpers JP1-JP4 the IO power source can be selected to either DC-5V Adapter (All Jumpers in the 1-2
position), or to Battery Charging mode which is the default setting (All Jumpers in the 2-3 position). In the default mode the
battery is charged with 5V from the DC Power Adapter, make certain that the battery is compliant! Figure 13 shows the default
battery setting and how to switch to DC-5V Adapter. When the ARTIK 710 Development Board is used with an external power
adapter make certain that you use a 5V-5A adapter with a 2.1x5.5mm plug.
