Additional jumpers are provided outside of the BoosterPack connector for additional external power connections for 3.3V or 5V. These can be used to supply an external board or for powering the LaunchPad with an external supply. When using these connection points, make sure that no other power supplies are connected.

  • JP4 is provided as an extra connection point for a 3.3V supply to be connected to the LaunchPad.
  • JP5 is provided as an extra connection point for a 5V supply to be connected to the LaunchPad.
