The 1.28 Inch Round TFT LCD Display Module is a compact, high-resolution IPS display designed for embedded systems, IoT devices, smart wearables, instrumentation, and graphical user interface (GUI) applications.
Featuring a 240×240 pixel full-color IPS panel driven by the GC9A01 controller, it delivers vibrant colors, excellent contrast, and wide viewing angles for crisp graphics and text.
The display communicates through a 7-pin SPI interface, enabling fast and reliable communication with popular development platforms including Arduino, ESP32, ESP8266, Raspberry Pi, STM32, and other 3.3V/5V microcontrollers. Its round form factor makes it ideal for smartwatches, circular dashboards, clocks, meters, and custom HMI projects.
With extensive online libraries, tutorials, and example codes available, the module is easy to integrate into DIY electronics, educational projects, and professional embedded system designs.
