Overview
The LILYGO T-Circle S3 is a compact development board built around the ESP32-S3R8, featuring a 0.75-inch circular TFT LCD (GC9D01N driver, 160×160 pixels) designed for round watchface and dial-style user interfaces. Despite its tiny footprint, it includes 16MB flash and 8MB PSRAM for complex animated UI applications.
The circular display enables natural watchface layouts, gauge meters, speedometers, and radar-style visualizations that look awkward on rectangular screens. The ESP32-S3's WiFi and BLE 5.0 connectivity enables real-time data display from servers, BLE devices, or Home Assistant.
Available in two variants: T-Circle S3 (full featured with ESP32-S3R8) and the bare T-Circle (stripped-down version at $8.40). Both are suitable for wearable development prototyping, miniature smart displays, and round-screen IoT dashboards.
