Round AMOLED Development Board

The LORDWORLD board combines an ESP32-S3 microcontroller with a 1.75inch round AMOLED touchscreen that resolves to 466×466 pixels and shows 16.7M colours. It includes the CO5300 display driver and CST9217 capacitive touch controller, and it communicates over a QSPI interface. The board supports Wi-Fi and BLE 5 connectivity and can run from an attached battery for portable operation.

Makers building wearable or handheld IoT prototypes

Developers creating compact smart watches, sensor hubs or voice-controlled gadgets will benefit from the round form factor, wide 178° viewing angle and on-board touch layer. The board also enables AI speech interaction with access to online large-model platforms such as DeepSeek and Doubao. Engineers who need a rectangular display, higher pixel density or a different wireless stack should consider other modules.

1.75inch 466×466 AMOLED touchscreen

The circular AMOLED panel is the single specification that determines fit: its 1.75inch diameter, 466×466 resolution and 16.7M colour depth define the visual area and touch surface available for your enclosure and UI design.
