LilyGO T-Display S3 Long ESP32-S3 Dev Board w/ 3.4-Inch Touch TFT

Description

The LilyGO T-Display S3 Long integrates Espressif’s high-performance ESP32-S3 microcontroller with a sizable 3.4-inch touchscreen, creating a complete platform for embedded GUI and IoT development. The dual-core LX7 processor, coupled with ample 8MB PSRAM, handles graphics rendering and wireless networking tasks simultaneously, enabling responsive touch interfaces and stable Wi-Fi/BLE connections.

Its elongated design accommodates the portrait-oriented display and provides a practical layout for prototyping handheld instruments or wall-mounted control panels. The board supports deep sleep modes for battery-powered operation, and the integrated QSPI interface ensures fast communication with the high-resolution TFT. Ready for deployment with Arduino, ESP-IDF, or MicroPython, it streamlines the development of visually rich, connected edge devices.
