## Description

## Overview

The LILYGO T-Display S3 Long is a distinctive ESP32-S3-based development board featuring an elongated 3.4-inch capacitive touch TFT LCD display with 180×640 pixel resolution, driven via QSPI. The extended aspect ratio makes it well-suited for scrolling dashboards, status bars, menu interfaces, and long-form data displays. Powered by the ESP32-S3R8 with 16MB Flash and 8MB PSRAM, it supports Wi-Fi 802.11 and Bluetooth 5 with BT mesh capability. The board includes battery voltage detection on IO02, onboard Boot and Reset buttons, and a battery switch for power management. It is available in a basic version and a with-shell variant that includes a protective enclosure. Development is supported via Arduino IDE and VS Code (PlatformIO).
