NX3224F028 - Nextion 2.8" Discovery Series หน้าจอสัมผัส HMI

The resistive touchscreen responds precisely even with my clumsy fingers, and the 64MHz STM32G0 handles my UI animations without any lag. I’ve had it running for two weeks straight on a bench power supply and the display stays crisp and readable at every angle.

Worked with it in an Arduino project for a week now and the resistive touch is actually pretty responsive once you calibrate it. The 2.8” screen is bright enough for a benchtop prototype, and I like that I can power it straight from the MCU headers, saves me an extra supply.

The 64MHz onboard MCU makes the touch response feel snappier than I expected for this price point. Took me an afternoon to wire it into a project with the bare board, but the Discovery series really cuts down on configuration fuss.
