3.3 Recommended Parts

Serial Communication

Figure 3: ESCCPC5V

The most common cable choice for the any GTT display, the Extended

Communication/ Power Cable offers a simple connection to the unit with

familiar interfaces. A DB9 and floppy power header provide all necessary

input to communicate to and power your display.

I2C Communication

For a more flexible interface to the GTT, especially with the I

C protocol,

a Breadboard Cable may be used. This provides a simple four wire

connection that is popular among developers for its ease of use in a

breadboard environment.

USB Communication

Figure 5: EXTMUSB3FT

The External Mini-B USB Cable is recommended for USB communication.

It will connect to the Mini-B style header on the unit and provide a

connection to a regular A style USB connector, commonly found on a PC.

Power

Figure 6: PCS

The standard power cable can be used to apply power to the GTT, either

in conjunction with the ESCCPC5V cable, or via a direct connection to the

Alternate Power Header. It connects to a standard PC power supply.

Mass Storage

Figure 7: EXTMUSB3FT

An External Mini-B USB Cable may also be used to access data within the

onboard SD card when removing the card itself is not possible. This

connection also provides power to the GTT and can be more convenient

than moving the SD card from one location to another.
