What is Nextion Display?

Nextion is a HMI Display with a TFT Touchscreen and Serial interface. Using the NEXTION Editor software, you can quickly develop the HMI GUI by using drag and drop components like graphics, text box, button, slider, etc.

Using UART interface with just two wires (Tx & Rx) you can connect the Nextion display to any Microcontroller via a 5 volt TTL interface. Using this UART interface you can connect the Nextion display to any Microcontroller like 8051, PIC, AVR, ARM Processors, STM Controllers, Arduino boards and even IoT based modules like NodeMcu (ESP8266 & ESP32), Particle Photon as well.

DNA Technology is official distributor for Nextion Display. You can buy all types of Nextion HMI display online from DNA
