3-wire Serial LCD Module (Arduino Compatible)

This 128x64 STN liquid crystal display module is powered by the ST7920 controller and connects easily to Arduino boards for interactive projects. It supports full graphics, English characters, and Chinese characters, making it ideal for students, hobbyists, and makers who require a clear visual interface.

Clear graphic and text display

The screen features a 128x64 pixel resolution with a wide 170-degree viewing angle on a 73x39mm visible display area. It displays crisp white text and graphics against a blue backlit background.

Dual parallel and serial interfaces
