A 1.28-inch round IPS LCD display module with an integrated capacitive touch panel. Featuring 240×240 resolution and 65K colours, the circular form factor is ideal for smartwatch-style interfaces, gauge displays, and interactive dashboards.
Built around the GC9A01 display driver (SPI) and CST816S capacitive touch controller (I2C), it minimises IO pin usage while providing responsive touch input. Waveshare provides example code for Raspberry Pi, Raspberry Pi Pico, Arduino, and STM32 platforms.

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- IPS
- IPS is a type of LCD panel that keeps colours and contrast more consistent when viewed from an angle. This matters for small displays that may be mounted in a dashboard, handheld project, or enclosure where the viewer is not always looking straight on.
- LCD
- LCD stands for liquid crystal display, a screen technology that uses a backlight and liquid crystals to show images or text. It matters because LCD modules usually need a display driver and enough controller pins or a bus interface to send image data.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
- STM32
- STM32 is a family of microcontroller chips commonly used in embedded electronics. Knowing a product uses an STM32 can help when looking at firmware updates, pin connections, or low-level serial control options.
- Transmittance
- Transmittance describes how much light passes through the display or touch panel layers. Higher transmittance can make the screen appear brighter or clearer for the same backlight power.
