Front of board showing power rails and connection
pins
Interconnections at back of board (normally
hidden). The 5-pin groups in each power rail are
interconnected. All other 5-pin groups are
isolated.
The gap at the center of the breadboard allows easy connection of electronic
components provided as dual-inline packages.
You use jumper cables between the Hub and the breadboard to power breadboard
components and to control or monitor them through program code. The Hub has 20
labeled pins, including 10 signal pins, 8 ground pins, one 3.3V power pin, and one 5.0V
power pin.

For a list of precautions to take while using the breadboard and its components, refer
to
General Precautions
(page 38).
To find sample programs and details about programming breadboard components on
the TI-Innovator™ Hub, see the TI-Innovator™ Technology eGuide (page ii).
Using an Auxiliary Power Source
Normally, the TI-Innovator™ Hub and its connected components draw power from the
host calculator or computer, through the
DATA
connector. Certain components, such as
the optional Servo Motor, require more power than a calculator can provide reliably.
The
PWR
connector on the Hub lets you connect an auxiliary power source. You can use
the TI Wall Charger or the External Battery Pack.
