2.3.3.2 Using the Supercap

After charging of the supercapacitor, you can move the J4 jumper to the Use setting and then unplug power. This connects the supercapacitor to the 3V3 rail without the charging resistor in between. At this point, the LaunchPad kit is being powered completely by the C6 supercapacitor.

For lowest power operation, make sure to disconnect the J101 jumpers so that the eZ-FET is not also powered by the C6 supercap.
