The breadboard and its components (purchased separately) let you build breadboard projects and connect them to the TI‑Innovator™ Hub through its Breadboard Connector pins.
The breadboard components include:
• | A breadboard and jumper cables for creating electrical connections. |
• | Addressable components, such as LEDs and sensors, that respond to |
• | Passive components, such as resistors, capacitors, and manual switches that are not directly addressable by the |
• | A Battery Holder that holds four AA batteries. Batteries are not included. |

The following TI CE graphing calculator(s) program uses Send and Wait commands to blink a specific LED on the breadboard.
Note: This program operates correctly only if the calculator is connected to the
PRGM: BLINKBB Send("CONNECT LED 1 TO BB1") For(N,1,10) Send("SET LED 1 ON") Wait 1 Send("SET LED 1 OFF") Wait 1 End Send("DISCONNECT LED 1") Note: If you are using TI‑Nspire™ CX technology, omit the parentheses, and change End to EndFor. |

The breadboard makes it easy to connect the electronic components of a project by inserting component leads and jumper cables into pins on the breadboard.
The pins are arranged in groups of 5. The 5 pins in each group are electrically connected to each other at the back of the board. You connect leads and cables together by inserting them into pins within the same group.
• | Power rails at the top and bottom are marked with red (+) and blue (–) stripes. The groups in each rail are electrically connected along the entire length of the stripe. |
• | The remaining 5-pin groups on the board are labeled with numbers and letters. Each group is electrically isolated from the others. |

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 (here).
