📺 Overview
The Nextion NX8048T050 is a 5.0-inch Basic Series HMI (Human Machine Interface) TFT LCD with integrated resistive touch. It’s part of the Nextion family of intelligent displays that handle graphics and touch processing onboard, letting you design rich GUIs with the Nextion Editor and control them via a simple UART (serial) interface from microcontrollers like Arduino, ESP32, Raspberry Pi, and others.
