TI-Innovator™ Hub Overview

The TI-Innovator™Hub lets you use your compatible TI graphing calculator or

TI-Nspire™CX computer software to control components, read sensors, and create

powerful learning experiences.

• You communicate with the Hub through TI Basic programming commands.

• Hosts that are compatible with TI-Innovator™Hub include:

- TI CE Family of Graphing Calculators (TI-83 Premium CE, TI-84 Plus CE, and

TI-84 Plus CE-T) with operating system version 5.3 or later installed. You also

need to install or update the Hub App, which contains the Hub menu.

- TI Nspire™ CX or TI Nspire™ CX CAS handheld with operating system version 4.5

or later installed

- TI Nspire™ computer software version 4.5 or later

•TI-Innovator™Hub. Communicates with the host, the Hub on-board components,

and connected external components. It also distributes power to external

components.

•TI-Innovator™ Components. These components, sold separately, include sensors,

motors, and LEDs that connect to the Hub through its I/O ports and breadboard

connector.

What's in the Box

TI-Innovator™Hub with On-Board

Components

ÀA Light Brightness Sensor at the bottom

of the Hub can be read as

"BRIGHTNESS" in Hub command strings.

ÁRed LED is addressable as "LIGHT" in

Hub command strings.

ÂSpeaker (at back of Hub, not shown) is

addressable as "SOUND" in Hub

command strings.

ÃRed-Green-Blue LED is addressable as

"COLOR" in Hub command strings.

Also visible on the face of the Hub are:

AGreen auxiliary power LED

BGreen power LED,

CRed error LED.

Built-in Ports

Left side-Three ports for collecting data or status

from input modules:

•IN1 and IN2 provide 3.3V power.

•IN3 provides 5V power.

Right side-Three ports for controlling output

modules:

•OUT1 and OUT2 provide 3.3V power.

•OUT3 provides 5V power.

Bottom-Light Brightness Sensor (described earlier)

and two ports:

•I2Cport connects to peripherals that use the I2C

communication protocol.

•DATAMini-B port, used with the appropriate

cable, connects to a compatible graphing

calculator or computer for data and power.

Top-Two connectors:

• USB-Micro connector (PWR) for auxiliary power

required by some components. Also used for

updating the Hub internal software.

• Breadboard Connector with 20 labeled pins for

communication with connected components. A

breadboard and jumper cables are included with

the TI-Innovator™ Breadboard Pack, sold

separately.

USB Cables

ÀUSB Unit-to-Unit (Mini-A to Mini-B)-Connects the Hub to a TI CE Graphing

Calculator or a TI-Nspire™CX Handheld.

ÁUSB Standard A to Mini-B-Connects the Hub to a computer running

TI-Nspire™CXSoftware.

ÂUSB Standard A to Micro-Connects the PWR port of the Hub to a TI approved

power source required by some peripherals.

Auxiliary Power

TIWallCharger - Supplies power through the

TI-Innovator™Hub for components, such as motors,

that require additional power.

The optional External Battery Pack can also provide

auxiliary power.

Note: An auxiliary power LED on the Hub indicates

when the Hub is receiving auxiliary power.

Connecting TI-Innovator™Hub

The TI-Innovator™Hub connects by a USB cable to a graphing calculator or computer.

The connection lets the Hub receive power and exchange data with the host.

Note: Some peripherals, such as motors, may require auxiliary power. For more

information, see Using an Auxiliary Power Source (page 27).

Connecting to a Graphing Calculator

1. Identify the "B" connector on the USB Unit-to-Unit (Mini-A

to Mini-B) cable. Each end of this cable is embossed with

a letter.

2. Insert the "B" connector into the DATA port at the bottom

of the TI-Innovator™Hub.

3. Insert the free end of the cable (the "A" connector) into the USB port on the

calculator.

4. Turn on the calculator if it is not already on.

The power LED on the Hub glows green to show that it is receiving power.

Connecting to a Computer Running TI-Nspire™CX Software

1. Identify the "B" connector on

the USB Standard A to Mini-B

cable for Windows®/Mac®.

Each end of this cable is

embossed with a letter.

2. Insert the "B" connector into

the DATA port at the bottom

of the TI-Innovator™Hub.

3. Insert the free end of the

cable (the "A" connector) into

a USB port on the computer.

The power LED on the Hub

glows green to show that it is

receiving power.

Updating the Hub Software

The TI-Innovator™Hub contains software, TI-Innovator™ Sketch, that interprets Hub

commands and communicates with on-board devices and connected modules. A Web-

based tool lets you update the Sketch. Updated versions contain bug fixes and ensure

that your TI-Innovator™Hub can communicate with the latest components.

To obtain the latest version of the TI-Innovator™ Sketch go to the following site:

https://education.ti.com/go/innovator

Questions About the Hub Software

What is the TI-Innovator™ sketch?

The ‘sketch’ is the software on the TI-Innovator™ Hub that communicates with the

graphing calculator, processes the commands, and controls the external components.

Do I need to update the sketch on the TI-Innovator™ Hub?

For best results always use the latest version of TI-Innovator™ sketch. To stay informed

on any updates to the TI-Innovator™ Hub, make sure you register your product at

education.ti.com/register or check the TI-Innovator™ website at

education.ti.com/go/innovator.

What is the latest version of the sketch?

For best results always use the latest version of TI-Innovator sketch. You can always

find the latest version of the sketch at education.ti.com/go/innovator.

Why would I update the sketch?

There are a couple of different reasons to upgrade the sketch.

1. To get the latest version from TI that may include new functionality.

2. To restore the TI sketch after loading a custom sketch – This is only needed by

advanced users who use an alternative sketch.

How do I load the sketch on the TI-Innovator™ Hub?

The sketch can be updated through the TI-Innovator Hub Update Software. This

software is a free download on the TI website.

Can I update multiple TI-Innovator Hubs at the same time?

The TI-Innovator Hub Update Software only allows updating a single Hub at a time.

However, the application is designed to allow you to update multiple Hubs without

having to re-launch the software.

Can the sketch that comes on the TI-Innovator™ Hub be edited to add functionality but

still work with the TI calculator? Is the sketch open source?

The code for sketch that is loaded on the TI-Innovator™ has not been published for

others to modify or edit. To maintain compatibility between the TI-Innovator™ Hub and

TI calculator products, only use the officially published sketch for TI-Innovator™ Hub.
