the schematic on the breadboard you linked explains it fairly well. the top row is for communication, INT/I2C, and the bottom row is for power, 5V/BAT, and GND/N.
the bottom row can be connected to power your device, either from the 5V AC->DC source, or the DC source supplied by the battery, or both. the GND/N is your return path
