3.2.1Power Switch and Power Supply Mode

Power can be supplied to the DVK in two modes: by a 5V AC-DC power adapter or the USB 5V power supply.

The jumper wire POWER-SWITCH is used to select a power supply mode. When pin1 and pin2 are connected, the USB 5V power supply is used; when pin2 and pin3 are connected, the 5V AC-DC power adapter is used. Only one mode can be selected at a same time. Once the development kit is powered on, the power indicator lights up.
