Designing a product with a colour TFT display and touch-screen does not have to be complex. To show how powerful and easy to use the new EA uniTFTs display series are various DEMOPACKs are available from MMS Electronics Ltd. The latest addition is the EA DEMOPACK-WiFiBT evaluation board with a 2.8” EA uniTFTs028-ATC smart display. The DEMOPACK-WiFiBT includes radio micro controller ESP32 to add WiFi and Bluetooth communication to the smart display. The project for the ESP32-WROOM-32 is fully documented and shows how to connect a Bluetooth keyboard to the display and another example using Wi-Fi shows how to retrieve weather information from https://openweathermap.org and display the weather forecast on the smart display. The familiar Arduino IDE is used to program the ESP32 processor.

The EA DEMOPACK-WiFiBT includes a 2.8" IPS TFT smart display with PCAP touch P/N: EA uniTFTs028-ATC.

The EA uniTFTs smart displays get projects off to a flying start. With integrated graphics controller, extensive graphics functions, USB, I²C, SPI and serial interfaces. The displays are ready to run without additional peripherals. The EA uniTFT(s) displays use improved IPS-Panels with AACS technology (All Angle Colour Stability). This means contrast and colours are retained even at extreme viewing angles. With high brightness typ. 1,000 cd/m² and above the displays are readable in direct sunlight. Optically bonded PCAP touch. The EA uniTFTs displays are available in size 2.0”, 2.8", 3.5" and 4.3".

All EA uniTFTs displays are programmed using the new uniTFTDesigner Windows software tool. The IDE boasts a simple drag-and-drop interface with simulator and numerous ready to run examples. 

The DEMOPACKs, displays and documentation are available from the MMS Electronics Ltd in Leeds.
