Our Review
After integrating the Nextion for Discovery Series HMI Touch Display 2.4 inch and 3.5 inch TFT LCD with Resistive Touch Screen STM32GO ARM Cortex-M0+ Processor Development Kit into several test builds, we found it to be a capable component for the price. Key specs include Display Type: TFT LCD, Resolution: 480x320, Size: 2.4 inch.
Display quality was good for the price. Colors are vibrant and viewing angles are acceptable. The SPI interface delivers fast enough refresh rates for UI elements and sensor dashboards.
Integration with Arduino and ESP32 was hassle-free. Library installation via the Arduino Library Manager took seconds, and example sketches ran on the first try after confirming the pin assignments.
Overall, the Nextion for Discovery Series HMI Touch Display 2.4 inch and 3.5 inch TFT LCD with Resistive Touch Screen STM32GO ARM Cortex-M0+ Processor Development Kit fills its role well. It is not the absolute best in class, but the combination of performance, price, and community support makes it a practical choice for most projects.
What We Like
- Full-color display for rich UI and image rendering
