Nextion 2.8″ HMI Display NX3224F028 Discovery Series

The Nextion NX3224F028 Discovery Series 2.8-inch HMI Display is a cost-effective TFT LCD resistive touchscreen designed to simplify Human Machine Interface (HMI) development. Featuring a 320 × 240 resolution, a 4MB Flash memory, and a 64MHz onboard MCU, it enables developers to create interactive graphical interfaces without placing heavy processing demands on the host microcontroller. It communicates over a simple TTL UART serial interface and is compatible with the free Nextion Editor, making GUI creation fast and easy.

Ideal for Arduino, ESP32, ESP8266, STM32, Raspberry Pi (via UART), PLCs, industrial automation, smart home systems, and IoT projects, the NX3224F028 delivers responsive touch control and reliable performance.
