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 and JP6 are provided as extra connection
points for a 3.3V supply to be connected to the LaunchPad.
- JP5 and JP7 are provided as extra connection
points for a 5V supply to be connected to the LaunchPad.
CAUTION: The F28P55x LaunchPad features a
VDD pin located on header JP4 that can only be used to monitor the voltage of the
1.2V VDD rail of the TMS320F28P550SJ9PZ device. This pin can not be used to supply
power to an external device nor connected to an external supply.
