Explorer 16 Development Board Connector J1
The two buck sections and one boost section of the Daughter Board can be controlled
using the Explorer 16 Development Board. Table 2-2 lists all the power and signal
connections on the Daughter Board J1 connector to the user interface with the
Explorer 16 Development Board. See Figure A-6 for the location of this connector.
