This 0.71″ round LCD module packs a 160 × 160 pixel IPS display with 65K colours into a tiny 20 × 22 mm footprint. Driven by the GC9D01 controller over a 4-wire SPI interface, it's easy to integrate with Raspberry Pi Pico, ESP32, Arduino, and other microcontrollers using minimal IO pins.
The round form factor and vivid colour output make it ideal for wearable tech, electronic eyes, compact instruments, and any project that needs a small but visually striking display. A convex lens is included to protect the screen and enhance visibility.

Jargon buster
Plain-language definitions for the technical terms used above.
- ESP32
- ESP32 is a family of microcontroller modules with built-in wireless features such as Bluetooth and WiFi. Knowing this product uses an ESP32-based module helps explain how it provides wireless serial communication and firmware update features.
- 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.
