2.9" 320x102 Graphic TFT Display 1U HMI using Serial RS232, TTL, USB, I2C, RS422 with GUI 7 key tactile keypad 5V power with 2GB memory and 32MB of RAM
Coming Soon eGTT29A

The eGTT29A is an intelligent 320 x 102 Graphic TFT display that features a full color TFT and integrated keypad designed to fit 1U applications. With the available - industry standard - communication protocols (serial RS232, TTL, I2C and USB TFT) and the incorporation of a seven key tactile keypad, communicating, controlling and interacting with the display is easily achieved.

Field updatable micro SD card stores font and bitmap files to liberate space and resources for use by the microcontroller, Arduino, or other HMI controller. Suitable for a wide range of applications, and with a resolution of 320 x 102, the eGTT29A is a complete display solution that will quickly become the bright fresh face of your machine or user interface.

Pair the eGTT series with our free software - GTT Designer - to design screens and user interactions quickly and easily. The software, which is compatible with all GTT displays, is a fully graphical, object-on, drag and drop suite with a library of built-in objects. Including: graphs, charts, buttons and animations. The interface was designed so no technical expertise is required to create a fully interactive user interface in minutes.
