## Description

## Overview

The LILYGO T-ETH Elite is a powerful ESP32-S3-based development board designed for advanced IoT gateway applications. It combines reliable wired Ethernet connectivity via the W5500 chip with the wireless flexibility of Wi-Fi and Bluetooth 5. The board supports Power-over-Ethernet (PoE), eliminating the need for a separate power supply in networked installations. An expansion shield system allows stacking LoRa (SX1262/SX1276/SX1278/SX1302) and LTE modules, enabling LoRaWAN gateway deployments. With 16MB flash and 8MB PSRAM, it is well-suited for demanding applications requiring network bridging, edge processing, and multi-protocol communication.
