•Nextion is a seamless Human Machine Interface (HMI) solution that provides a control and visualization interface between a human and a process, machine, application or device, it is the best solution to replace traditional LCD and LED. Replace the Nixie tube. It is mainly used in the Internet of Things (IoT) or consumer electronics.
•Nextion consists of a hardware part (a series of TFT cards) and a software part (the Nextion editor). The Nextion TFT board uses only one serial port for communication. Save users the hassle of wiring. It is easy to adapt the Nextion family HMI to existing projects. Users just need to provide it with a UART.
•You can power Nextion 3.5 from the 5V pin on the microcontroller, but this is not recommended. Working with insufficient power can damage the screen, so please use the power board that comes with nextion. See the image for use.
•NX4832T035 is a powerful 3.5 inch HMI. Features include: 3.5 inch 480 x 320 TFT resistive touchscreen display, 16MB Flash, 2KB RAM, 65,000 colors. Viewing area: 73.44mm (L) × 48.96mm (W); Uploading a TFT file via an SD card is faster than a 4-pin serial connection, but the credit card is in FAT32 format and does not exceed 32GB.
