NX4832F035 – Nextion 3.5 inch Discovery Series HMI Touch Screen
Nextion is an HMI solution that combines a built-in processor and touch-memory display with the Nextion Editor software. Using the Nextion Editor software, one can quickly develop the HMI GUI by dragging and dropping components (graphics, text, buttons, sliders, etc.) and coding the way components will interact on the screen using ASCII-based instructions. The Nextion HMI screen connects to the external MCU via TTL Serial (5V, TX, RX, GND) to provide event notifications that the external MCU can process. The external MCU can easily update the progress and return the status to the Nextion screen using simple ASCII-based text. Compared to the Basic Series, the Discovery Series has better MCU performance, the same functions as Basic, and a lower price.
