LilyGO T-RGB 2.1-Inch Round Touch Display ESP32-S3 Board

Description

The LilyGO T-RGB development board integrates the powerful ESP32-S3 microcontroller with a high-resolution, round capacitive touchscreen, creating a unified platform for embedded GUI and IoT applications. Its ESP32-S3R8 chip delivers dual-core processing at 240 MHz, coupled with substantial 8MB flash and 16MB PSRAM, enabling the handling of complex graphics, touch events, and wireless protocols simultaneously without performance bottlenecks.

Engineered for interactive projects, the board’s 2.1-inch TFT display uses an ST7701S driver IC and an 18-bit RGB parallel interface to deliver full-color graphics with smooth refresh rates. The integrated capacitive touch layer allows for intuitive user input, making it suitable for control panels, status monitors, and portable instrumentation. The board’s low-power sleep modes and robust wireless stack (802.11 b/g/n Wi-Fi and Bluetooth LE 5.0) ensure efficient operation in battery-powered, connected devices.
