LILYGO T-Display-S3 ESP32 WiFi and Bluetooth Development Board
The LILYGO T-Display-S3 ESP32 is a compact development board built around the ESP32-S3R8 dual-core LX7 microprocessor, providing Wi-Fi and Bluetooth connectivity for wireless embedded and IoT applications. It integrates a 1.9-inch full-color TFT display driven by the ST7789V controller, two programmable buttons, USB connectivity for programming, and interfaces for connecting external peripherals. The board provides 16 MB Flash and 8 MB PSRAM and supports Arduino IDE and MicroPython development.
The integrated display and wireless connectivity make the T-Display-S3 suitable for projects that require both a user interface and network communication in a compact form factor. It can be used for IoT dashboards, wireless controllers, portable monitoring devices, sensor interfaces, BLE applications, and ESP32-S3 prototyping. The board also provides I²C connectivity through a STEMMA QT/Qwiic-compatible interface and a JST-GH connector for additional peripherals or power-related connections.
