Under the name "EA DEMOPACK," DISPLAY VISIONS GmbH offers its 2.8-inch color mini-TFT graphic displays with a touch interface in combination with various sub-boards. These allow for the development of ready-to-use, more or less customized applications. For example, in addition to the EA uniTFTs028-ATC mini-touch display, the "EA DEMOPACK-WIFIBT" also includes a sub-board with the popular ESP32 radio microcontroller. This can be used to connect the mini-display via Wi-Fi or Bluetooth.
The supplied sample programs allow you to immediately create standalone applications, such as a weather station, a Bluetooth keyboard for smartphones or tablets, or individual keyboard shortcuts for your computer. Using the uniTFTDesigner graphical development environment, you can easily adapt the samples to your own needs, without requiring in-depth programming knowledge, or even develop your own applications.
In simple terms, it can produce individual displays, move objects on the screen, modify readings during display, automatically zoom in on important parameters, or smoothly fade controls. The ESP32 radio microcontroller is fully documented and uses the Arduino IDE as its programming interface.
The EA uniTFTs028-ATC LEDs are designed for the demands of everyday industrial use. They have a lifespan of at least 50,000 hours and a wide operating temperature range from -20°C to +70°C. The brightness is 1,000 cd/m². As with all its products, DISPLAY VISIONS GmbH guarantees long-term availability and comprehensive support.
