Full Product Description

Bring Your Circular UI Ideas to Life

Stop constraining your IoT and wearable projects to traditional rectangular screens. The Waveshare 1.28-inch Round LCD Display Module is engineered specifically for developers and hobbyists who want to create sleek, modern interfaces like smartwatches, circular gauges, and dynamic status indicators. Powered by the reliable GC9A01 driver and featuring an IPS display panel, it guarantees crystal-clear visuals and vibrant color reproduction from virtually any viewing angle.

Efficient 4-Wire SPI Communication

Working with microcontrollers often means battling for available I/O pins. This module utilizes a highly efficient 4-wire SPI interface, which dramatically reduces the number of pins required for high-speed display communication. This leaves your controller's remaining GPIO pins free for integrating additional sensors, buttons, or wireless modules without compromising on display refresh rates.

Broad Microcontroller Compatibility

Whether you are a student exploring STEM concepts, a maker prototyping a wearable, or a corporate engineer developing custom diagnostic tools, this display adapts to your workflow. With a flexible 3.3V / 5V operating voltage, it seamlessly connects to a massive ecosystem of boards, including Raspberry Pi, Jetson Nano, Arduino, and STM32. Plus, comprehensive development resources and ready-to-use code examples ensure you spend less time troubleshooting and more time creating.
